下面我们就动手来创建一个线程,使用Thread类创建线程时,只需提供线程入口即可。线程入口使程序知道该让这个线程干什么事,在C#中,线程入口是通过ThreadStart代理(delegate)来提供的,你可以把ThreadStart理解为一个函数指针,指向线程要执行的函数,当调用Thread.Start()方法后,线程就开始执行ThreadStart所代表或者说指向的函数。
打开你的VS.net,新建一个控制台应用程序(Console Application),下面这些代码将让你体味到完全控制一个线程的无穷乐趣!
//ThreadTest.cs using System; using System.Threading; namespace ThreadTest { public class Alpha { public void Beta() { while (true) { Console.WriteLine("Alpha.Beta is running in its own thread."); } } }; public class Simple { public static int Main() { Console.WriteLine("Thread Start/Stop/Join Sample"); Alpha oAlpha = new Alpha(); //这里创建一个线程,使之执行Alpha类的Beta()方法 Thread oThread = new Thread(new ThreadStart(oAlpha.Beta)); oThread.Start(); while (!oThread.IsAlive); Thread.Sleep(1); oThread.Abort(); oThread.Join(); Console.WriteLine(); Console.WriteLine("Alpha.Beta has finished"); try { Console.WriteLine("Try to restart the Alpha.Beta thread"); oThread.Start(); } catch (ThreadStateException) { Console.Write("ThreadStateException trying to restart Alpha.Beta. "); Console.WriteLine("Expected since aborted threads cannot be restarted."); Console.ReadLine(); } return 0; } } }
