.NET Framework Standard Library Annotated Reference, Volume 1: Base Class Library and Extended Numerics Library

Example

using System;
using System.Threading;

namespace Samples
{
  public class ThreadStateExceptionSample
  {
    public static void StartHere()
    {
      Console.WriteLine("Thread: starting");
      Console.WriteLine("Thread: finishing");
    }
    public static void Main()
    {
      Thread t = new Thread(
                   new ThreadStart(StartHere));
      t.Start();
      Thread.Sleep(1000);
      Console.WriteLine("2) Thread state: {0}",
                        t.ThreadState);
      try
      {
        t.Suspend();
      }
      catch(ThreadStateException e)
      {
        Console.WriteLine("Exception: {0}", e);
      }
    }
  }
}

The output is

 Thread: starting Thread: finishing 2) Thread state: Stopped Exception: System.Threading.ThreadStateException: Thread is not running; it cannot be suspended. at System.Threading.Thread.SuspendInternal() at System.Threading.Thread.Suspend() at Samples.ThreadStateExceptionSample.Main() ...
