using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading; namespace ThreadDemo { class Program { static void Main(string[] args) { string threadState; Thread t = new Thread(ThreadState.WorkerFunction); t.Start(); while (t.IsAlive) { Console.WriteLine("Still waiting.I'm going back to sleep."); Thread.Sleep(200); } threadState = t.ThreadState.ToString(); Console.WriteLine("ThreadState is "+threadState); Console.ReadLine(); } } public class ThreadState { public static void WorkerFunction() { string threadState; for (int i = 0; i < 10; i++) { if (i % 2 == 0) { threadState = Thread.CurrentThread.ThreadState.ToString(); Console.WriteLine("Worker:"+threadState); } } Console.WriteLine("Worker Function Complete"); } } }

输出：

Still waiting.I'm going back to sleep.
Worker:Running
Worker:Running
Worker:Running
Worker:Running
Worker:Running
Worker Function Complete
ThreadState is Stopped

Main()方法继续与新线程一起执行，因为处理器在这两者之间切换。然后，使用新建线程的IsAlive属性，确定线程是否还在执行。继续测试这个变量，当工作线程处于激活状态时，主线程将继续睡眠200毫秒，然后唤醒主线程，并测试工作线程是否仍处于激活状态。
