We provide support for the C# language in all major operating systems. We also provide instructions on how to get your project started in a number of common development environments. Select your operating system and preferred development environment below, and follow the instructions to get your project running with Phidgets.

If you do not know which development environment you want to use, or your development environment of choice is not listed, we recommend starting with .NET CLI as the simplest path to getting your code running. Visual Studio is the most popular way to build C# projects, but it also has a steep learning curve.

Once you have set up your development environment to run with Phidgets, we recommend you follow our guide on Phidget Programming Basics. The guide will showcase the fundamentals of programming with Phidgets, with examples in C#.

Visual Studio is an IDE provided by Microsoft that can be used to develop code in a wide variety of programming languages, including C#.

Requirements

First, make sure you have the following installed:

● Phidgets Drivers for Windows

● Microsoft Visual Studio

Nuget

The Phidget22.NET library is now available on nuget.org here. Nuget is the recommended way to install and use the .NET library in Visual Studio. The nuget package bundles the C library on Windows, so there are no other prerequisites that need to be installed. The nuget package adds targets for .NET Core and .NET Standard, so it should be usable from almost any .NET environment which also supports the C library.

Using Phidgets in Your Programs

There are two ways you can use Phidgets in Visual Studio. You can either start from a sample project provided by our code sample generator, or you can start a new project from scratch.

Select your preferred method below for instructions:

Language - C#

Linux with Mono

Welcome to using Phidgets with C#! By using C#, you will have access to the complete Phidget22 API, including events.

Mono is an open-source programming environment that aims to make Microsoft .NET applications available across all operating systems.

Requirements

First, make sure you have the following installed:

● Phidgets Drivers for Linux

● Mono

● A copy of Phidget22.NET.dll

You need our C development libraries in order to use Mono. You can install them with:

apt-get install libphidget22-dev

If you don't already have Mono installed, you can get it with:

apt-get install mono-complete

Setting UDev Rules

By default, Linux will not allow regular users to access physical hardware, as a security feature. This means that you must grant yourself root privileges via sudo to run Phidgets code.

sudo mono program.exe

To avoid having to use sudo every time, you can set up a rules file to allow it automatically using the vendor code for Phidget USB devices. Create a text file called 99-libphidget22.rules containing the following line:

SUBSYSTEMS=="usb", ACTION=="add", ATTRS{idVendor}=="06c2", ATTRS{idProduct}=="00[3-a][0-f]", MODE="666"

Mode 666 means every user has permission to read and write to the specified devices. Next, move this file to /etc/udev/rules.d. Now you can run code that uses Phidgets as a regular user without sudo.

Finding Code Samples

To find the code sample to use for your Phidget, navigate to the Code Samples page and select your device from the drop-down menu.

-===Description of Library Files===
-C# programs on Windows depend on the following files, which the installers above put onto your system:
-*'''phidget22.dll''' contains the actual Phidget library, which is used at run-time. By default, it is placed in C:\Windows\System32.
-*'''Phidget22.NET.dll''' is the Phidget library for .NET framework 2.0 or higher. Your compiler has to know where this file is. By default, it is placed into C:\Program Files\Phidgets\Phidget22. You can either point your compiler to that location, or copy and link to it in a directory for your project workspace.
-You can optionally install the following files:
-*'''Phidget22.NET.XML''' provides the IntelliSense in-line documentation for the .NET library in Visual Studio/MonoDevelop. This documentation is also visible in the Object Browser in Visual Studio. By default, it is placed into C:\Program Files\Phidgets.
-Running the examples and writing your own code can be fairly compiler-specific, so we include instructions for each compiler below.
-===Visual Studio 2015===
-Microsoft makes free versions of Visual Studio available known as Express Editions. The Express editions are suitable for most applications, but are limited in features for more complex applications. Please see [//www.visualstudio.com/en-us Microsoft Visual Studio] for more information.
-====Use Our Examples====
-Please start by downloading the examples and unpacking them into a folder. Since the examples were written in Visual Studio 2015, you will need to use Visual Studio 2015 or later in order to run the examples. To load all projects in Visual Studio, go to File → Open → Project, and open AllExamples/AllExamples.sln.
-The easiest way to confirm that your environment is set up properly will be to compile and run the HelloWorld C# example.
-Start by setting the HelloWorld project as your start up project.
-The only thing left to do is to run the example! Click on Debug → Start Debugging. Please note that the projects, by default try to find the Phidget22.NET.dll in the C:\Program Files\Phidgets\Phidget22. If you have it installed in another location, please change the path to the file's location accordingly. If you are receiving an error message regarding that the namespace Phidget22 cannot be found, please re-add the reference to Phidget22.NET.dll. Please see the [[#Write Your Own Code|Write Your Own Code]] section for details.

-After confirming that the HelloWorld example is working, you can proceed to run the example for your device. The source file will be named the same as the software object you want to use with your device. A device will often use more than one software object, so you may need to run multiple examples to learn how to use your device (for example, a Phidget Spatial uses the Accelerometer, Gyroscope, Magnetometer, and Spatial software objects). If you are not sure what the software objects for your device are, find your Phidget on our [http://www.phidgets.com webpage], and then check the API documentation for it.

-To load all projects in MonoDevelop/Xamarin Studio, go to File → Open, and open AllExamples/AllExamples.sln
-This will load all of the examples available for C#, and then you can set your main project to be the one that matches your device. If you are running under the .NET framework, you can use either the full or simple examples. Otherwise, if you are running under the Mono framework, please only use the simple examples. The full examples uses Windows Forms, which is not completely compatible with Mono's Gtk#.
-[[Image: CSharp MonoDevelop setStartup.png|link=]]
-The only thing left to do is to run the examples! Right click the project, and click on Run With and select the target framework. Please note that the projects, by default try to find the Phidget22.NET.dll in the C\Program Files\Phidgets\Phidget22. If you have it installed in another location, please change the path to the file's location accordingly. If you are receiving an error message regarding that the namespace Phidget22 cannot be found, please re-add the reference to Phidget22.NET.dll. Please see the [[#Write Your Own Code|Write Your Own Code]] section for details.

-Once you have the C# examples running, we have a [[#Edit the Examples|teaching section]] below to help you follow them.
-====Write Your Own Code====
-When you are building a project from scratch, or adding Phidget function calls to an existing project, you'll need to configure your development environment to properly link the Phidget .NET library. To begin:
-. Create a new C# .NET Console project with a descriptive name such as PhidgetTest.
-[[Image: CSharp MonoDelevop NewProject.png|link=|600px]]
-[[Image: CSharp MonoDelevop NewProject2.png|link=|600px]]
-. Add a reference to the Phidget .NET library.
-[[Image: CSharp MonoDelevop EditReferences1.png|link=]]
-. Select Phidget22.NET.dll. If you used our installer, by default, this file is placed in C:\Program Files\Phidgets\Phidget22. If it is in another location, please change the path to the file's location accordingly.
-[[Image: CSharp MonoDelevop EditReferences2.png|link=|600px]]
-. Then, in your code, you will need to include the Phidget .NET library:
-<syntaxhighlight lang='CSharp'>
-  using Phidgets;
-  using Phidgets.Events;
-</syntaxhighlight>
-The project now has access to the Phidget function calls and you are ready to begin coding.
-The same [[#Edit_the_examples|teaching]] section which describes the examples also has further resources for programming your Phidget.
-== OS X ==
-===Use Our Examples===
-The first thing you are going to need to do is install Mono (Note that Mono is only available for Intel Macs and not PowerPC). You will need both the SDK and the runtime.
-Then, you will need the Phidget .NET libraries. These are part of the Windows library zip file download:
-{{WindowsQuickDownloads}}
-Extract the library zip file. Descriptions for the files are available on the OS - Windows page, but for now we only need the Phidget22.NET.dll file to run the Phidget C# examples in Mono. So remember where you unzipped these Windows libraries - you will need to copy the Phidget22.NET.dll file into your example directory shortly.
-Next, you'll want to download and extract the Phidget C# Examples (For Windows, not for .NET Compact):
-*[[#Example_Code|C# Examples for Windows]]
-One more thing needs to be done before you can compile and run the examples. You need to set up a special configuration file so that Mono knows where to find the phidget22.dll. Since Mac does not use dll's you need to redirect it to the appropriate file. Create a new file in the same directory as the example you wish to compile and name it Phidget22.NET.dll.config. Put the following into the file:
-<syntaxhighlight lang='xml'>
-  <configuration>
-	<dllmap dll="phidget22.dll" target="/Library/Frameworks/Phidget22.framework/Versions/Current/Phidget22" />
-  </configuration>
-</syntaxhighlight>
-All that is left is to compile and run the code. When compiling, you need to link to the Phidget library. As the Phidget22.NET file is an "additional assembly" in C#/Mono, you can link to the assembly using the -r "reference" switch:
-<syntaxhighlight lang='bash'>
-gmcs Program.cs -r:Phidget22.NET.dll
-</syntaxhighlight>
-This will compile a *.exe file - in this case, Program.exe. This you can then run under Mono:
-<syntaxhighlight lang='bash'>
-mono Program.exe
-</syntaxhighlight>
-If you will be compiling with an IDE such as GTK# or MonoDevelop, we don't have explicit instructions by IDE for OS X. However, you will probably find the MonoDevelop section in the Windows portion above useful.
-===Write Your Own Code===
-When writing your code from scratch, you start it as you would any C# code on OS X. In your .cs source code file, you must include a reference to the Phidget Library:
-<syntaxhighlight lang='CSharp'>
-using Phidgets;
-using Phidgets.Events;
-</syntaxhighlight>
-Then, you would compile your completed C# code the same way as the examples above.
-Mono also has a few different IDEs which you can use to develop code, and these are especially useful if you are doing GUI development. We provide instructions for MonoDevelop - one such IDE - being used under [[OS - Windows|Windows]].
-To learn how to write your own code for your Phidget, and to learn more about our API, we have a [[#Edit the Examples|teaching section]] to help you follow the provided C# examples and which has resources such as the API reference.
-== Linux ==
-C# has support on Linux through the Mono framework.
-===Use Our Examples===
-The first step in using C# with Phidgets on Linux is to make sure that you have all of Mono installed. Although you probably have already done this if you're a C# programmer, you want to make sure you have all of the packages you'll need. Try:
-<syntaxhighlight lang='bash'>
-sudo apt-get mono-complete
-</syntaxhighlight>
-Next, you'll want to install the main Phidget Libraries. Compile and install them as explained on the main Linux page. That Linux page also describes the different Phidget files, their installed locations, and their roles.
-Then, you will need the Phidget .NET libraries. These are part of the Windows library zip file download:
-{{WindowsQuickDownloads}}
-Extract the library zip file. Descriptions for the files are available on the OS - Windows page, but for now we only need the Phidget22.NET.dll file to run the Phidget C# examples in Mono. So remember where you unzipped these Windows libraries - you will need to copy the Phidget22.NET.dll file into your example directory shortly.
-Next, you'll want to download and extract the Phidget C# Examples (For Windows, not for .NET Compact):
-*[[#Example_Code|C# Examples for Windows]]
-To check that your Linux, Phidget, and Mono setup is all working together, you'll want to run the C# examples. Specifically, you'll want to run the simple C# examples. You can either use the HelloWorld program that will work with any Phidget, or you can find the source code for your device. The source file will be named the same as the software object for your device. If you are not sure what the software object for your device is, find your Phidget on our [http://www.phidgets.com webpage], and then check the API documentation for it.
-Let's say you're running the Temperature Sensor example (for the 1048 or 1051). The source code for the example is in the directory:
-    TemperatureSensorExamples → TemperatureSensor-simple → TemperatureSensor-simple → Program.cs
-Other examples will be in directories named appropriately for their software object name. Once you have found the example you want to run, copy the Phidget22.NET.dll file that you unzipped earlier into that example directory where the Program.cs file is.
-Then, compile the code. When compiling, you need to link to the Phidget library. As the Phidget22.NET file is an "additional assembly" in C#/Mono, you can link to the assembly using the -r "reference" switch:
-<syntaxhighlight lang='bash'>
-  gmcs Program.cs -r:Phidget22.NET.dll
-</syntaxhighlight>
-This will compile a *.exe file - in this case, Program.exe. This you can then run under Mono:
-<syntaxhighlight lang='bash'>
-sudo mono Program.exe
-</syntaxhighlight>
-Remember that the sudo is needed unless you have your [[OS_-_Linux#Setting_udev_Rules|udev rules set on your Linux system]].
-If you will be compiling with an IDE such as GTK# or MonoDevelop, we don't have explicit instructions by IDE for Linux. However, you will probably find the MonoDevelop section in the Windows portion above useful.
-===Write Your Own Code===
-When writing your code from scratch, you start it as you would any C# code on Linux, such as within a text editor like Emacs, Vi, Gedit, or Kate. In your .cs source code file, you must include a reference to the Phidget Library:
-<syntaxhighlight lang='CSharp'>
-using Phidgets;
-using Phidgets.Events;
-</syntaxhighlight>
-Then, you would compile your completed C# code the same way as the examples above.
-Mono also has a few different IDEs which you can use to develop code, and these are especially useful if you are doing GUI development. We provide instructions for MonoDevelop - one such IDE - being used under [[OS - Windows|Windows]].
-To learn how to write your own code for your Phidget, and to learn more about our API, we have a [[#Edit the Examples|teaching section]] to help you follow the provided C# examples and which has resources such as the API reference.
-== Edit the Examples ==
-By following the instructions for your operating system and compiler above, you probably now have a working example and want to understand it better so you can change it to do what you want. This teaching section has resources for you to learn from the examples and write your own.
-Your main reference for writing C# code will be the {{Phidget22API}} Manual.
-=== Code Snippets ===
-The following code snippets describe how to do various general tasks with Phidgets. You should be able to find places in the examples where these snippets exist, and modify them to suit your requirements.
-==== Step One: Initialize and Open ====
-The Open() function opens the software object, but not hardware. So, it is not a guarantee you can use the Phidget immediately.
-For example, if we were using an Digital Input as our device, the create and open calls would look like this:
-<syntaxhighlight lang=csharp>
-using Phidget22;
-using Phidget22.Events;
-namespace Program
-{
-    class Code
-    {
-        static void Main(string[] args)
-        {
-            try
-            {
-                // Declare a DigitalInput object
-                DigitalInput device = new DigitalInput();
-                // Hook in any event handlers
-                // ...
-                // Open the device
-                device.Open();
-            }
-            catch (PhidgetException ex) { Console.WriteLine(ex.Description); }
-        }
-    }
-}
-</syntaxhighlight>
-==== Step Two: Wait for Attachment (plugging in) of the Phidget ====
-To use the Phidget, it must be plugged in (attached). We can handle this simply by calling open with a number as a parameter in place of the basic open. This function works for any Phidget. This will block until a connection is made to the Phidget, or the specified timeout is exceeded:
-<syntaxhighlight lang=C>
-device.Open(5000);
-</syntaxhighlight>
-Sometimes, it makes more sense to handle the attachment via an event. This would be in instances where the Phidget is being plugged and unplugged, and you want to handle these incidents. Or, when you want to use event-driven programming because you have a GUI-driven program. In these cases, an event-driven code snippet to handle the attachment might look something like this:
-<syntaxhighlight lang=CSharp>
-void attachEventHandler(object sender, Phidget22.Events.AttachEventArgs e) {
-{
-  Phidget attachedDevice = (Phidget)sender;
-  int serialNumber = attachedDevice.DeviceSerialNumber;
-  string deviceName = attachedDevice.DeviceName;
-  Console.WriteLine("Hello Device {0},  Serial Number: {1}!", deviceName, serialNumber.ToString());
-}
-</syntaxhighlight>
-And the code to set up the event handler within the code opening your device might look like:
-<syntaxhighlight lang=CSharp>
-//Code for -creating- device here....
-device.Attach += attachEventHandler;
-//Code for -opening- device here....
-</syntaxhighlight>
-==== Step Three: Do Things with the Phidget ====
-We recommend the use of event driven programming when working with Phidgets. This allows the program to execute other tasks until the Phidget generates a new event. You can hook a custom function into an event trigger like this, using a Digital Input Phidget as an example:
-<syntaxhighlight lang=csharp>
-device.StateChange += input_change;
-</syntaxhighlight>
-The input_change method is defined as follows:
-<syntaxhighlight lang=csharp>
-void input_change(object sender, Phidget22.Events.DigitalInputStateChangeEventArgs e) {
-    textBox1.Text = "State: " + e.State;
-}
-</syntaxhighlight>
-Some values can be directly read and set on the Phidget. These functions can be used inside a polling loop as an alternative to event driven programming. The line inside the loop would be something like this, after which you could do something with the value:
-<syntaxhighlight lang=csharp>
-bool val = device.State;
-device.State = true;
-</syntaxhighlight>
-==== Step Four: Close and Delete ====
-At the end of your program, be sure to close your device.
-<syntaxhighlight lang=csharp>
-private void Form1_FormClosing(object sender, FormClosingEventArgs e)  {
-    Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
-        If device.Attached Then
-            device.Close()
-        End If
-    End Sub
-}
-</syntaxhighlight>
