Socket异步接收发送问题
想问下socket 异步接收事件问题 在服务器跟客户端发生过一次数据交换后需要先通过Shutdown() 跟Close释放一次连接清除通信缓存么？ 这样的话服务器跟客户端通信岂不是每次通信前都需要连接？

 public void Receive(IAsyncResult iar)//接收数据的方法

         {

             //try

             //{

                 String DateString = string.Empty;



                 ObjectSocket os = (ObjectSocket)iar.AsyncState;



                 Socket handler = os.worksocket;



                 int Read = handler.EndReceive(iar);



                 DateString = Encoding.ASCII.GetString(os.BufferDate, 0, ObjectSocket.BufferSize);



                 if (DateString.Contains("HEADEND"))

                 {

                     int headlleght = Encoding.ASCII.GetBytes(Search_string(DateString, "HEADSTART", "HEADEND")).Length + Encoding.ASCII.GetBytes("HEADSTART").Length + Encoding.ASCII.GetBytes("HEADEND").Length;

                     DateAnalysis(Search_string(DateString, "HEADSTART", "HEADEND"), headlleght, os);

                 }

                    os.worksocket.BeginReceive(os.BufferDate, 0, ObjectSocket.BufferSize, 0,

              new AsyncCallback(Receive), os);//接收完后回调该方法 等待下一次数据接收

             //}

             //catch (Exception e)

             //{



             //}



         }

以上代码是接收后直接回调该客户端没清空缓存 请问我是应该重新断开连接 还是在这步直接清除缓存就成？如果只要清除缓存 应该如何清除？
