如何使两个子线程先后依次执行？
Thread   t1   =   new   Thread(new   ThreadStart(Method1));
t1.Start();
Thread   t2   =   new   Thread(new   ThreadStart(Method2));
t2.Start();
t1   执行完之后t2执行

------解决方案--------------------
private System.Threading.ManualResetEvent mre = new System.Threading.ManualResetEvent(true);

void button_onclick(....)
{
Thread t1 = new Thread(new ThreadStart(Method1));
Thread t2 = new Thread(new ThreadStart(Method2));
mre.Reset();
t1.Start();
mre.WaitOne();
t2.Start();
}

void Method1()
{
....
mre.Set();
}

------解决方案--------------------
依次执行？
ThreadPool.QueueUserWorkItem 线程池
------解决方案--------------------
在线程2的执行函数前面加上一句Thread1变量名.Join();
