我下段代碼連接時(shí)老是出異常“所請(qǐng)求的地址無(wú)效”出現(xiàn)在 socket.Bind(ipEndPoint)。誰(shuí)能幫我看看啊，急急急急//打開(kāi)TCP端口        private void btnConTcp_Click(object sender, EventArgs e)        {            try            {                IPAddress ip=IPAddress.Parse(tbIp.Text);//162.168.200有效的                IPEndPoint ipEndPoint=new IPEndPoint(ip, int.Parse(tbTCPPort.Text));                socket = new Socket(AddressFamily.InterNetwork, SocketType.Raw, ProtocolType.IP);                 socket.Blocking = false; //置socket非阻塞狀態(tài)                 socket.Bind(ipEndPoint); //綁定套接字                 socket.Connect(ipEndPoint);                if(socket.Connected)                  lbMessage.Items.Insert(0,"與主機(jī):" + tbIp.Text + ",端口:" + tbTCPPort.Text + "連接成功");                else                  lbMessage.Items.Add("連接失敗");            }            catch(Exception ex)            {                lbMessage.Items.Insert(0,"連接失敗："+ex.Message);            }        }
