Abort()方法用于销毁线程。
运行时通过抛出ThreadAbortException中止线程。无法捕获此异常,控制将被发送到finally块(如果有)。
以下是显示如何销毁线程的示例-
using System; using System.Threading; namespace MultithreadingApplication { class ThreadCreationProgram { public static void CallToChildThread() { try { Console.WriteLine("Child thread starts"); //做一些工作,例如数到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("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); //现在中止孩子 Console.WriteLine("In Main: Aborting the Child thread"); childThread.Abort(); Console.ReadKey(); } } }
输出结果
In Main: Creating the Child thread Child thread starts 0 1 2 In Main: Aborting the Child thread Thread Abort Exception Couldn't catch the Thread Exception
