各位，端口问题强力在线求助！

Question

各位，求助了，我监听本机一个端口，把这个端口接收到的数据发送到另外的计算机的指定端口上，现在有时可以接收到，有时要出问题，
        //回发数据给客户端
        private void RecieveCallBack(IAsyncResult ar)
这个是接收完毕的函数，函数实现可能有问题，麻烦各位给看下

不是，首先帮看下这个处理有问题没？
       //回发数据给客户端
        private void RecieveCallBack(IAsyncResult ar)
        {
            Socket s = (Socket)ar.AsyncState;
            int read = s.EndReceive(ar);            if (read > 0)
            {
                string strContent = Encoding.ASCII.GetString(buffer, 0, read);
                //sendMsg(strContent);
                tbNews.AppendText("接收到" + strContent.Length + "字节，内容:\r\n-----" + strContent + "\r\n");
            }        }
