怎么在异步通信中实现event和delegate
我是个委托和事件的新手，请各位大侠指导下我以下的问题，谢谢我有个类声明了事件和委托
//接口方法
void StatusQryReq(string requesterNumber, StatusCheckResp status);
//委托
public delegate void StatusCheckResp(bool bFlag, string strStatusCheckResp);
//事件
public event StatusCheckResp StatusCheckEvent;
以下是我的异步ReadCallback
public void AcceptCallback(IAsyncResult ar)
{
allDone.Set();
Socket listener = (Socket)ar.AsyncState;
Socket handler = listener.EndAccept(ar);
StateObject state = new StateObject();
state.workSocket = handler;
handler.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0,
new AsyncCallback(ReadCallback), state);
}
public void ReadCallback(IAsyncResult ar)
{
if (ar.IsCompleted)
{
StateObject state = (StateObject)ar.AsyncState;
Socket handler = state.workSocket;
int bytesRead = handler.EndReceive(ar);
if (bytesRead > 0)
{
state.sb.Append(Encoding.ASCII.GetString(
state.buffer, 0, bytesRead));
string strRespReqNum = rowaDataFactory.parseRowaCmd(state.sb.ToString());
string strCallbackEvent = callbackMgmt.GetCallbackEvent(strRespReqNum);
//以下怎么去写事件和那个委托进行绑定？
}
}
} 通信 asynchronous delegate event --------------------编程问答--------------------
--------------------编程问答--------------------
if(StatusCheckEvent!=null)
{
StatusCheckEvent(true,"str");
}
在调用AcceptCallback之前注册StatusCheckEvent事件就行了。
补充：.NET技术 , C#
