怎么强行停止BEGINRECEIVE过程（不是关闭SOCKET哦）

C# WinForm异步TCP双端工程：IOCP线程隔离与粘包处理 TCP通信是网络编程的基础协议，其字节流特性决定了必须处理粘包、分包、连接管理及线程安全等核心问题。在Windows Forms这类UI框架中，同步Socket操作易导致界面冻结，而简单异步回调又面临UI线程争用、上下文丢失和GC压力等工程陷阱。基于.NET Framework原生Begin/End异步模型，结合I/O完成端口（IOCP）调度机制，可实现非阻塞、高并发、可调试的生产级TCP通信。本文详解WinForm环境下TcpClient/TcpListener的线程隔离设计、定长消息头分帧策略、连接池与阅读详情

private void ReceiveA(Socket client)
{
try
{

StateObject state = new StateObject();
state.workSocket = client;
client.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReceiveACallback), state);
}
catch (Exception e)
{

}
}

private void ReceiveACallback(IAsyncResult ar)
{
try
{

StateObject state = (StateObject)ar.AsyncState;
Socket client = state.workSocket;
int bytesRead = client.EndReceive(ar);

//here, client has some logic problem, it keeps receiving
if (bytesRead > 0)
{

response = Encoding.ASCII.GetString(state.buffer, 0, bytesRead);
state.sb.Append(response);//ascii string get append

if (response.IndexOf("val")> -1 || response.IndexOf("\r\n> ") > -1)
{

if (state.sb.Length > 1) //get ascii code out true
{
response = state.sb.ToString();
state.sb.Clear();
}
receiveDone.Set();
}

else
{

// Get more data
client.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReceiveACallback), state);

}
}
}
catch{}
}

可以看到在RECEIVEACALLBACK中，由于一次接受数据不够，利用ELSE称述中的CLIENT.BEGINRECEIVE继续接受数据。但是我不想让这一过程一直接收下去，请问有什么办法强行停止吗？（不能关闭SOCKET,因为我还要继续发送新的命令来得到接收数据）。。。
谢谢了，前面发的一帖没描述好，被忽视了。。。。
