  Example14_4.cs illustrates the use of thread-local storage

using System;
using System.Threading;

public class Example14_4 

  // the WriteError method writes error info from the current thread
  public static void WriteError()
    Console.WriteLine("Error number = " + Thread.GetData(Thread.GetNamedDataSlot("ErrNo")));
    Console.WriteLine("Error source = " + Thread.GetData(Thread.GetNamedDataSlot("ErrSource")));

  // the SetError method sets a random error number
  public static void SetError() 
    Random r = new Random();
    Thread.SetData(Thread.GetNamedDataSlot("ErrNo"), r.Next(100));
    Thread.SetData(Thread.GetNamedDataSlot("ErrSource") ,Thread.CurrentThread.Name);

  public static void Main() 
    // allocate some named data slots

    // create and start a second thread
    Thread t2 = new Thread(new ThreadStart(SetError));
    t2.Name = "t2";

    // create a third thread
    Thread t3 = new Thread(new ThreadStart(SetError));
    t3.Name = "t3";

    // clean up the data slots
