如何点击按钮停止线程

Question

点击button1执行
public void DoWork()
        {
            for (int i = 0; i < 100; i++)
            {
                Thread.Sleep(500);
                RealRead();
            }        }
我想按button2把上面那个停掉 

Answer 1

if (Thread.ThreadState == ThreadState.Running)
         Thread.Abort();

Answer 2

  Thread t=new Thread(new ThreadStart());
            t.Start();
            t.Abort();

Answer 3

if (Thread.ThreadState == ThreadState.Running) 
Thread.Abort();

Answer 4

public void DoWork() 
        { 
            Thread.Abort();
        } 
会引发ThreadAbortException异常，适当处理一下。
