线程无法终止的问题

Question

启用了个死循环来监听端口，可是在退出的时候用abort方法不能终止线程，下面是我的代码： 
public void Listen(int port) 
        { 
            try 
            { 
                isStopThread = false; 
                UDP_Server_Port = port; 
                UDP_Server = new UdpClient(port); 
                thUdp = new Thread(new ThreadStart(GetUDPData)); 
                thUdp.Start(); 
            } 
            catch(Exception e) 
            { 
                throw new Exception(e.Message); 
            } 
        } 
private void GetUDPData() 
        { 
            
            while (!isStopThread) 
            { 
                try 
                { 
                    byte[] RData = UDP_Server.Receive(ref _Server); 
                    if (DataArrival != null) 
                    { 
                        DataArrival(RData, _Server.Address, _Server.Port); 
                    } 
                    Thread.Sleep(0);                 } 
                catch (Exception e) 
                { 
                    throw new Exception(e.Message); 
                    if (Sock_Error != null) 
                    { 
                        Sock_Error(e.Message); 
                    } 
                } 
            } 
        } 
终止线程代码： 
while (thUdp.ThreadState != System.Threading.ThreadState.Stopped) 
                { 
                    //thUdp.Interrupt(); 
                    thUdp.Abort(); 
                    thUdp.Join(); 
                    //thUdp = null; 
                } 
                //thUdp.ThreadState = System.Threading.ThreadState.Stopped; 
                
                UDP_Server.Close(); 这里thUdp.ThreadState 的状态一直是AbortRequested  晕的不行  有没有强行终止线程的方法 
小弟现在没有多少分了，等以后有了给大哥们补上，先谢了!

while (thUdp.ThreadState != System.Threading.ThreadState.Stopped) 
                { 
                    //thUdp.Interrupt(); 
                    thUdp.Abort(); 
                    thUdp.Join(); 
                    //thUdp = null; 
                } 
                //thUdp.ThreadState = System.Threading.ThreadState.Stopped; 
                
                UDP_Server.Close(); 把while改成if试试看吧...
我的做法是ThreadState为Running的时候就调用Abort,调用完就做别的,不要管太多条件判断,千万不要循环调用.那样人可以多活几秒种^_^

我开始的时候直接thUdp.Abort()线程，但是abort后线程的状态一直是AbortRequested，而不是stopped 
这样的话下面的UDP_Server.Close(); 就会抛出线程正在终止的异常了   加了这个while是我在调试的时候想看一下状态到底是什么样的  呵呵  误导大家了！
