Example

using System;
using System.Threading;

namespace Samples
{
  public class TimeoutSample
  {
    public static void StartHere()
    {
      Console.WriteLine("Thread starting");
      Thread.Sleep(1000);
      Console.WriteLine("Thread finishing");
    }
    public static void Main()
    {
      Thread t = new Thread(
                   new ThreadStart(StartHere));
      Console.WriteLine("Main starting");
      t.Start();
      TimeSpan ts = new TimeSpan(100);
      Console.WriteLine("Joined: {0}",
                        t.Join(ts));
      Console.WriteLine("Joined: {0}",
                        t.Join(Timeout.Infinite));
      Console.WriteLine("Main finishing");
    }
  }
}

The output is

Main starting
Thread starting
Joined: False
Thread finishing
Joined: True
Main finishing
