SocketAsyncEventArgs

独立开发的游戏服务器端敲完了（告别BUG!!!!） 写个博客（总结）出来

介绍（大概都知道） SocketAsyncEventArgs是.NET Framework 3.5出的

SocketAsyncEventArgs常用的成员

Buffer

BytesTransferred

SocketError

UserToken

BytesTransferred

SetBuffer

Completed

///只列出了主要方法~

Accept监听

bool b= socket.AcceptAsync(e); if (!b) { //注意这里要上锁 lock(e) { ProcessAccept(e); } } Receive监听 <pre name="code" class="csharp">bool b= userToken.connect.ReceiveAsync(userToken.ReceiveEventArgs); if (!b) { lock (userToken) //这里也要加锁 { ProcessReceive(userToken.ReceiveEventArgs); } } <pre name="code" class="csharp">//判断网络消息接收是否成功 if (userToken.ReceiveEventArgs.BytesTransferred > 0 && userToken.ReceiveEventArgs.SocketError == SocketError.Success) { //...处理消息和再次开启消息监听 }

IO_Completed <pre name="code" class="csharp">lock (userToken) { if (e.LastOperation == SocketAsyncOperation.Receive) { ProcessReceive(e); } else if (e.LastOperation == SocketAsyncOperation.Send) { ProcessSend(e); } } Send <pre name="code" class="csharp">sendSAEA.SetBuffer(buff, 0, buff.Length); bool result = connect.SendAsync(sendSAEA); if (!result) { sendProcess(sendSAEA);//这里只是个回调 } //之前在插入数据的时候我也上锁了 否则会数据混乱 尴尬... <img alt="得意" src="http://static.blog.csdn.net/xheditor/xheditor_emot/default/proud.gif" />
