- msdn中的流程如下：
但在msdn中的代码中，同步Accept的部分没有开始新一轮Accept(没有调用StartAccept)，不清楚原因？
private void ProcessAccept(SocketAsyncEventArgs e)
{
Interlocked.Increment(ref m_numConnectedSockets);
Console.WriteLine("Client connection accepted. There are {0} clients connected to the server", m_numConnectedSockets);
// Get the socket for the accepted client connection and put it into the
// ReadEventArg object user token
SocketAsyncEventArgs readEventArgs = m_readWritePool.Pop();
((AsyncUserToken)readEventArgs.UserToken).Socket = e.AcceptSocket;
// As soon as the client is connected, post a receive to the connection bool willRaiseEvent = e.AcceptSocket.ReceiveAsync(readEventArgs);
if (!willRaiseEvent)
{
ProcessReceive(readEventArgs);
}
}
在AcceptAsync的异步完成回调中，可以看出他调用了StartAccept()
// This method is the callback method associated with Socket.AcceptAsync
// operations and is invoked when an accept operation is complete
void AcceptEventArg_Completed(object sender, SocketAsyncEventArgs e)
{
ProcessAccept(e);
// Accept the next connection request
StartAccept(e);
}
