c#事件委托需要返回int,1表示成功，0表示失败

public delegate void DialOutEventHandler(object sender, AxLib._OnDialOutEvent e)
public AxLib._OnDialOutEvent(int i)
应该怎么实现呢，
AxLib._OnDialOutEvent e=new AxLib._OnDialOutEvent(object sender, AxLib._OnDialOutEvent e);
int ai=e.i; --------------------编程问答-------------------- http://www.cnblogs.com/BeginnerClassroom/archive/2009/01/11/1373689.html --------------------编程问答-------------------- 不知道你什么意思。

委托你懂么？ --------------------编程问答--------------------         public AxLib.LinkSocket axLink;
