在执行的线程上调用sleep()方法来指定的毫秒暂停当前线程。从面使其他线程有机会开始执行。

using system;
using system.threading;
public class mythread
{
    public void thread1()
    {
        for (int i = 0; i < 10; i++)
        {
            string curtime = datetime.now.tostring();
            console.writeline("thread1 at "+ curtime + " => "+ i);
            thread.sleep(500);// 挂起半秒
        }
    }
}
public class threadexample
{
    public static void main()
    {
        mythread mt = new mythread();
        thread t1 = new thread(new threadstart(mt.thread1));
        thread t2 = new thread(new threadstart(mt.thread1));
        t1.start();
        t2.start();
    }
}

执行上面示例代码，得到以下结果 -
