Powershell window form how to create OnTimeEvent()?

Question

Hello.

I create simple windows form application in powershell

Add-Type -AssemblyName System.Windows.Forms
$Form = New-Object system.Windows.Forms.Form
$Form.ShowDialog()

How to add this code to it?
In C# windows form application it look's like that:

using System.Collections.Generic;
using System.Runtime.InteropServices;
using System.Timers;
using System.Windows.Forms;
using System;

namespace WindowsFormsApp1Csh
{
    public partial class Form1 : Form
    {

        private void Form1_Load(object sender, EventArgs e)
        {
            t = new System.Timers.Timer();
            t.Interval = 10;
            t.Elapsed += OnTimeEvent;
            t.Start();
        }


private void OnTimeEvent(object sender, ElapsedEventArgs e)
        {
            Invoke(new Action(() =>
            {
                Console.WriteLine("Hello");
            }));

        }
}

Can i semohow create a public void metho or something like that?

Thanks for help.

Using Create a Windows Forms application from the command line you can create a Windows Forms program outside of Powershell using any plain text editor. Except you will need to find the C# compiler to execute it; for example it might be in:

"C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe"

Have a look at this.

In C# windows form application it look's like that:

If you are trying to build a GUI application, and if you already have C# code snippets, then just write it in C#. As SimpleSamples noted, and as I replied to one of your earlier threads, use the free "Community" version of Visual Studio.

Is there a reason that you trying to do this in Powershell?

The following works for me. Note that in Windows there is a difference between console applications and GUI (form) applications. You can use System.Timers.Timer in a console application. If you need a form then you need to use Visual Studio (not Visual Studio Code; the names sound alike but the tools are very different) to write the program(s). The following is an example in Timer Class.

$code = @"  
using System;  
using System.Timers;  
  
namespace Example {  
public class Program  
{  
   private static System.Timers.Timer aTimer;  
     
   public static void Main()  
   {  
      SetTimer();  
  
      Console.WriteLine("\nPress the Enter key to exit the application...\n");  
      Console.WriteLine("The application started at {0:HH:mm:ss.fff}", DateTime.Now);  
      Console.ReadLine();  
      aTimer.Stop();  
      aTimer.Dispose();  
        
      Console.WriteLine("Terminating the application...");  
   }  
  
   private static void SetTimer()  
   {  
        // Create a timer with a two second interval.  
        aTimer = new System.Timers.Timer(2000);  
        // Hook up the Elapsed event for the timer.   
        aTimer.Elapsed += OnTimedEvent;  
        aTimer.AutoReset = true;  
        aTimer.Enabled = true;  
    }  
  
    private static void OnTimedEvent(Object source, ElapsedEventArgs e)  
    {  
        Console.WriteLine("The Elapsed event was raised at {0:HH:mm:ss.fff}",  
                          e.SignalTime);  
    }  
}  
}

Hello @Sam of Simple Samples & @MotoX80 .
Thanks for answars, it help me.
This is my final code.

Add-Type -TypeDefinition @"  
using System;  
using System.ComponentModel;  
using System.Drawing;  
using System.Windows.Forms;  
using System.Timers;  
  
namespace Test

    public class Form1 : Form  
    {  
        public Button button1;  
    System.Timers.Timer t;  
        public Form1()  
        {  
            button1 = new Button();  
            button1.Size = new Size(40, 40);  
            button1.Location = new Point(30, 30);  
            button1.Text = "Click me";  
            this.Controls.Add(button1);  
            button1.Click += new EventHandler(button1_Click);  
            Form1_Load();  
  
        }  
      
        private void Form1_Load()  
        {
