Cannot wait process running until end

Question

I have one aspx code behind page, that uses a process (p) to call an application (exe file) as following the code:

p.Start();
while(!p.HasExited)
{
    Thread.Sleep(2000);
}
p.Dispose();

The while loop to take waiting of 2s, but is always throwing the exception like below:

System.Threading.ThreadAbortException: Thread was being aborted.
   at System.Threading.Thread.SleepInternal(Int32 millisecondsTimeout)
   at Insyma.ContentUpdate.XmlReader.DoSleep()

At the statement Thread.Sleep(2000). So anybody can help me some solutions. Thanks so much,

Answer 1

Use AutoResetEvent

class BasicWaitHandle
{
   static EventWaitHandle _waitHandle = new AutoResetEvent (false);
   static void Main()
   {
       new Thread (Waiter).Start();        
       _waitHandle.WaitOne(); //wait for notification
       //Do operartion
   }

   static void Waiter()
   {
      //Do operations
      _waitHandle.Set(); //Unblock
   }
}

Seems like you need some Fire and Forget pattern. thread is exiting because once page is been rendered its instance is prone to be disposed.. so this is may be what you need.

ThreadPool.QueueUserWorkItem(o => FireAway());

private void FireAway()
{
p.Start();
while(!p.HasExited)
{
    Thread.Sleep(2000);
}
p.Dispose();

}

Simplest way to do a fire and forget method in C#?
