====Configure your project====
When you are building a project from scratch, or adding Phidget functionality to an exisiting project, you'll need to configure your development environment to properly link the Phidget .NET library.
To include the Phidget .NET library, simply add the following lines to your code:
<syntaxhighlight lang='CSharp'>
using Phidget22;

</syntaxhighlight>
The project now has access to Phidgets. Next, view the [[#Write Code | write your own code]] section located below.
== Write Code ==
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.
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>

Getting Phidgets Sample Code

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.
