thread.interrupt only working once

[Lost User]

nd am having a problem in my application that ive been able to replicate using the code below. I want the function TestTimeout to run only at certain times so im using Thread.Sleep(Timeout.Infinite); to stop it. I'm interrupting the thread using the button below it works once however has no effect afterwards ? What should happen is it should display the message then sleep again until interpreted

private static Thread TimeoutThread;
private void Form1Load(object sender, EventArgs e)
{
var Job = new ThreadStart(TestTimeout);
TimeoutThread = new Thread(Job) { IsBackground = true };
TimeoutThread.Start();
}

     private static void TestTimeout() 
     { 
         MessageBox.Show("Run"); 
         try 
         { 
             Thread.Sleep(Timeout.Infinite); 
         } 
         catch (ThreadInterruptedException) 
         { 
             TestTimeout(); 
         } 
     } 

     private void button1\_Click(object sender, EventArgs e) 
     { 
         TimeoutThread.Interrupt(); 
     }

Can anyone tell me how to resolve this issue

I think that recursive call to TestTimeout is causing some problems. Does something like this do what you want (I have added a spinwait to simulate some work being done).

    private static Thread TimeoutThread; 
    private void Form1\_Load(object sender, EventArgs e)
    {
        ThreadStart Job = new ThreadStart(TestTimeout);
        TimeoutThread = new Thread(Job) { IsBackground = true };
        TimeoutThread.Start(); 
    }

    private static void TestTimeout() 
    {
        while (true)
        {
            MessageBox.Show("Starting Work");
            try
            {
                Thread.SpinWait(100000000);
                MessageBox.Show("Finished Work");
                Thread.Sleep(Timeout.Infinite);
            }
            catch (ThreadInterruptedException)
            {

            }                 
        }

    }

    private void button1\_Click(object sender, EventArgs e)
    {
        TimeoutThread.Interrupt();
    }

check out once that may be your form_load event called many times..
