创建线程

线程是聊聊类线通过扩展 Thread 类创建的。扩展的程常 Thread 类调用 Start() 方法来开始子线程的执行。

下面的用操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();         }     } 

当上面的源码库代码被编译和执行时,它会产生下列结果:

In Main: Creating the Child thread Child thread starts 

管理线程

Thread 类提供了各种管理线程的聊聊类线方法。

下面的程常实例演示了 sleep() 方法的使用,用于在一个特定的用操时间暂停线程。

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  seconds",聊聊类线                               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,云服务器它会产生下列结果:

In Main: Creating the Child thread Child thread starts Child Thread Paused for 5 seconds Child thread resumes 

销毁线程

Abort() 方法用于销毁线程。程常

通过抛出 threadabortexception 在运行时中止线程。用操这个异常不能被捕获,聊聊类线如果有 finally 块,程常控制会被送至 finally 块。用操

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 10                 for (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("Couldnt 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 thread Child thread starts 0 1 2 In Main: Aborting the Child thread Thread Abort Exception Couldnt catch the Thread Exception
