代码如下：
/// <summary>
       /// 声明获取事件的委托
       /// </summary>
       private delegate void SynReceive();
       /// <summary>
       /// 线程接收函数
       /// </summary>
        
       public void Receive()
       {
           
           try
           {
               string strRcv = "";
              // 声明字节数组，一次接收数据的长度为1024字节
               byte[] RcvBuffer = new byte[1024];
               //循环读取，直到接收完所有数据
               while (true)
               {
                   int bytes = socket.Receive(RcvBuffer, RcvBuffer.Length, 0);
                   //读取完成后退出循环
                   if (bytes <= 0)
                       break;
                   //将读取的字节数转换为字符串
                   strRcv += Encoding.ASCII.GetString(RcvBuffer,bytes,0);
                  
                   if (!txtRcv.InvokeRequired)
                   {
                       txtRcv.AppendText(strRcv);

                   }
                   else
                   {
                       txtRcv.Invoke(new SynReceive(Receive));
                   }

               }
               
           }
