创建线程
线程是通过扩展 Thread 类创建的。扩展的 Thread 类调用 Start() 方法来开始子线程的执行。
下面的程序演示了这个概念：.
class ThreadCreationProgram{public static void CallToChildThread(){Console.WriteLine("Child thread starts");}static void Main(string[] args){ThreadStart childref = new ThreadStart(CallToChildThread);Console.WriteLine("In Main: Creating the Child thread");Thread childThread = new Thread(childref);childThread.Start();Console.ReadKey();}}
当上面的代码被编译和执行时，它会产生下列结果：
In Main: Creating the Child threadChild thread starts
管理线程
Thread 类提供了各种管理线程的方法。
下面的实例演示了 sleep() 方法的使用，用于在一个特定的时间暂停线程。
class ThreadCreationProgram{public static void CallToChildThread(){Console.WriteLine("Child thread starts");// 线程暂停 5000 毫秒int sleepfor = 5000;Console.WriteLine("Child Thread Paused for {0} seconds",sleepfor / 1000);Thread.Sleep(sleepfor);Console.WriteLine("Child thread resumes");}static void Main(string[] args){ThreadStart childref = new ThreadStart(CallToChildThread);Console.WriteLine("In Main: Creating the Child thread");Thread childThread = new Thread(childref);childThread.Start();Console.ReadKey();}}
当上面的代码被编译和执行时，它会产生下列结果：
In Main: Creating the Child threadChild thread startsChild Thread Paused for 5 secondsChild thread resumes
销毁线程
Abort() 方法用于销毁线程。
通过抛出 threadabortexception 在运行时中止线程。这个异常不能被捕获，如果有 finally 块，控制会被送至 finally 块。
下面的程序说明了这点：
class ThreadCreationProgram{public static void CallToChildThread(){try{Console.WriteLine("Child thread starts");// 计数到 10for (int counter = 0; counter <= 10; counter++){Thread.Sleep(500);Console.WriteLine(counter);}Console.WriteLine("Child Thread Completed");}catch (ThreadAbortException e){Console.WriteLine("Thread Abort Exception");}finally{Console.WriteLine("Couldn't catch the Thread Exception");}}static void Main(string[] args){ThreadStart childref = new ThreadStart(CallToChildThread);Console.WriteLine("In Main: Creating the Child thread");Thread childThread = new Thread(childref);childThread.Start();// 停止主线程一段时间Thread.Sleep(2000);// 现在中止子线程Console.WriteLine("In Main: Aborting the Child thread");childThread.Abort();Console.ReadKey();}}
当上面的代码被编译和执行时，它会产生下列结果：
In Main: Creating the Child threadChild thread starts012In Main: Aborting the Child threadThread Abort ExceptionCouldn't catch the Thread Exception
