回调函数必须是静态的吗?

Question

那么静态函数可以调用非静态函数么?

Answer 1

public class TcpServer
{
   protected AsyncCallback AcceptCallback=new AsyncCallback(ProcessAccept); //委托字段
   public void try(){}          //非静态
   public void BeginServer()
        {
          listeningSocket.BeginAccept(AcceptCallback,this); //调用回调函数
        }
   protected static void ProcessAccept(IAsyncResult ar)  //回调函数
         {
           TcpServer tmpServer=(TcpServer)ar.AsyncState;  //ar.AsyncState就是前面的this
           tmpServer.try()   //静态调用非静态
          }
}错了别找我啊~~
