如何取消已经被绑定的连接,释放端口出来啊?



while (true)
            {   trysockerr = false;
                Thread.Sleep(50);
                try
                {    
                    sock.Bind(ipep);

                }
                catch
                {
                    trysockerr = true;
                }
                sock.Close();//这里不是释放了吗?为什么不行??请高手制教.
            Console.WriteLine(trysockerr);
           
          //  Listener.ReceiveFrom(aaa,ref ep);

            if (trysockerr)
            {
                byte[] aaa = new byte[58];
                Socket Listener = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
                Listener.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, 1);
                Listener.Bind(ipep);
                Listener.SendTo(aaa, ipep2);
            }
              
            } --------------------编程问答-------------------- 简单点可以不用管下面的if语句:
试过了,就第一个是false,其他的一直都是true,证明端口并没有释放出来,请高手解决一下这个问题,先谢啦.~
