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 Mono 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#.

===Nuget===
The Phidget22.NET library is now available on nuget.org [https://www.nuget.org/packages/Phidget22.NET/ here]. Nuget is the recommended way to install and use the .NET library. 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.
== Getting Started with C# ==
Welcome to using Phidgets with C#! By using C#, you will have access to the complete {{Phidget22API}}, including events. We also provide example code in C# for all Phidget devices.
If you are developing for Windows, keep reading. Otherwise, select your operating system to jump ahead:
*[[#macOS | macOS]]
*[[#Linux | Linux]]

===Visual Studio===
====Use Our Examples====
One of the best ways to start programming with Phidgets is to use our example code as a guide. In order to run the examples, you will need to download and install [https://www.visualstudio.com/ Microsoft Visual Studio].
Now that you have Microsoft Visual Studio installed, select an example that will work with your Phidget:
*{{SampleCode|CSharp|C# Examples}}
Open the example project and start the example by pressing the ''Start'' button:
[[File:Csharp_visualstudio_run.png ‎|link=|center]]
The application will open the Phidget, list basic information about the Phidget, and demonstrate the Phidget's functionality. Here is an example of a Digital Output channel on a RFID Phidget:
[[File:Csharp_visualstudio_rfid.PNG|link=|center]]
You should now have the example up and running for your device. Play around with the device and experiment with some of the functionality. When you are ready, the next step is configuring your project and writing your own code!
=====VINT Hub=====
If you are trying to connect to one of the VINT hub ports directly rather than to a VINT device connected through a VINT hub then there is one additional step.  There is a isHubPort property of the Phidget class that must be set before calling open.  It defaults to false but in this case it will need to be set to true.  In our examples this is done via command line though in practice you can just set it before calling open.  To add command line parameters to your project in Visual Studio, you can go to the Project->Properties screen.  Under the Debug section there is a field to enter command line parameters for startup.  Use "-h" to make sure isHubPort is set before open is called and then you should be good to go.
[[File:Csharp_visualstudio_commandLineParameters.png|link=|center]]
====Configure Your Project====
When you are building a project from scratch, or adding Phidget functionality to an existing project, you'll need to configure your development environment to properly link the Phidget .NET library. To begin:
Create a new Windows Forms Application project:

==Write Code==
{{WriteCode_Intro|C#}}
==== Step One: Initialize and Open ====
You will need to declare your Phidget object in your code. For example, we can declare a digital input object like this:
<syntaxhighlight lang=csharp>
DigitalInput ch;
</syntaxhighlight>
Next, the Phidget object needs to be initialized and opened:
<syntaxhighlight lang=cSharp>
ch = new DigitalInput();
ch.Open();
</syntaxhighlight>
Although we are not including it on this page, you should include error handling for all Phidget functions. Here is an example of the previous code with error handling:
<syntaxhighlight lang=cSharp>
try{
  ch = new DigitalInput();
  ch.Open();
}catch(PhidgetException ex){
  Console.WriteLine("Error: " + ex.Description);
}
</syntaxhighlight>
==== Step Two: Wait for Attachment of the Phidget ====
Simply calling open does not guarantee you can use the Phidget immediately. To use a Phidget, it must be plugged in (attached). We can handle this by using event driven programming and tracking the attach events. Alternatively, we can modify our code so we wait for an attachment:
<syntaxhighlight lang=CSharp>
ch = new DigitalInput();
ch.Open(5000); //wait for attach for 5 seconds, if not time out
</syntaxhighlight>
Waiting for attachment will block indefinitely until a connection is made, or until the timeout value is exceeded.
To use events, we have to modify our code slightly:
<syntaxhighlight lang=CSharp>
ch = new DigitalInput();
ch.Attach += onAttachHandler;
ch.Open();
</syntaxhighlight>
Next, we have to declare the function that will be called when an attach event is fired - in this case the function ''onAttachHandler'' will be called.
<syntaxhighlight lang=CSharp>
void onAttachHandler (object sender, Phidget22.Events.AttachEventArgs e){
  attachedText.Text = "Attached";
}
</syntaxhighlight>
==== Step Three: Do Things with the Phidget ====
We recommend the use of event driven programming when working with Phidgets. In a similar way to handling an attach event as described above, we can also add an event handler for a state change event:
<syntaxhighlight lang=csharp>
ch = new DigitalInput();
ch.Attach += onAttachHandler;
ch.StateChange += onStateChangeHandler;
ch.Open();
</syntaxhighlight>
This code will connect a function and an event. In this case, the ''onStateChangeHandler'' function will be called when there has been a change to the devices input. Next, we need to create the ''onStateChangeHandler'' function:
<syntaxhighlight lang=cSharp>
void onStateChangeHandler(object sender, Phidget22.Events.DigitalInputStateChangeEventArgs e) {
    stateText.Text = "State: " + e.State;
}
</syntaxhighlight>
If events do not suit your needs, you can also poll the device directly for data using code like this:
<syntaxhighlight lang=cSharp>
stateText.Text = "State: " + ch.State;
</syntaxhighlight>
==== Step Four: Close and Delete ====
At the end of your program, be sure to close your device.
<syntaxhighlight lang=cSharp>
ch.Close()
</syntaxhighlight>

Next we'll use this base project to run some Phidgets sample code. Go to the product page for your Phidget and go to the Code Samples tab. Select C# from the language drop-down and use the check boxes to modify the example if you'd like.

Click the copy button in the corner of the code sample and paste it into the Program.cs for your HelloWorld program, overwriting the existing code.

Compile and Run

Once you've pasted the sample code into the .cs file and saved, you need to add the Phidgets .NET package to your project:

dotnet add package Phidget22.NET

Then you can re-build the project using

dotnet run

Success! The project is now using Phidgets.

What's Next?

Now that you've set up Phidgets in your programming environment, you should read our guide on Phidget Programming Basics to learn the fundamentals of programming with Phidgets.

Language - C#

MacOS with dotnet CLI

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

The dotnet command-line interface is the quickest way to start programming in C# on MacOS and Linux.

Installing dotnet CLI

First, make sure you have the Phidgets Drivers for MacOS installed (see this page for installation instructions).

Next, visit Microsoft's .NET page and download .NET after confirming compatibility with your version of MacOS.

Click on the .pkg file once it's finished downloading, and follow the steps to install the .NET SDK.

Setting up a New Project

Open Finder and go to Utilities -> Terminal. Create a new C# project using the following command:

dotnet new console -o helloworld

This will create a new C# console application in a folder named helloworld in your current directory. Next, type cd helloworld to enter the folder, and type:

dotnet run

If everything installed properly, the application will build and you'll see 'Hello, World!' printed in the terminal. You can open Program.cs using the text editor to see the code.
