Run Powershellscript in C#

You could place your PowerShell script into a separate file and call it on a bound event.

// When a button is clicked...private void Button_Click(object sender, EventArgs e){    // Create a PS instance...    using (PowerShell instance = PowerShell.Create())    {        // And using information about my script...        var scriptPath = "C:\\myScriptFile.ps1";        var myScript = System.IO.File.ReadAllText(scriptPath);        instance.AddScript(myScript);        instance.AddParameter("param1", "The value for param1, which in this case is a string.");        // Run the script.        var output = instance.Invoke();        // If there are any errors, throw them and stop.        if (instance.Streams.Error.Count > 0)        {            throw new System.Exception($"There was an error running the script: {instance.Streams.Error[0]}");        }        // Parse the output (which is usually a collection of PSObject items).        foreach (var item in output)        {            Console.WriteLine(item.ToString());        }    }}

In this example, you would probably make better use of the passed in event arguments, and perform some better error handling and output logging, but this should get you down the right path.

Note that running your current script as-is will only declare your Food function, but won't actually run it. Make sure there is a function invocation in your script or C# code.
