.Net线程足迹(三）——IsAlive属性

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。
