C#使用线程池创建线程

using System;

using System.Threading;

public class Example

{

    public static void Main()

    {

        // Queue the task.

        ThreadPool.QueueUserWorkItem(ThreadProc);

        Console.WriteLine("Main thread does some work, then sleeps.");

        Thread.Sleep();

        Console.WriteLine("Main thread exits.");

    }

    // This thread procedure performs the task.

    static void ThreadProc(Object stateInfo)

    {

        // No state object was passed to QueueUserWorkItem, so stateInfo is null.

        Console.WriteLine("Hello from the thread pool.");

    }

}

// The example displays output like the following:

//       Main thread does some work, then sleeps.

//       Hello from the thread pool.

//       Main thread exits.
