EventHandler委托与自定义委托

//1、  
public delegate void UcSavedEventHanler(bool isSuccess);  
//2、  
public event UcSavedEventHanler OnUcSaved;  
//3、  
UcEditor1(用户控件).OnUcSaved+= new UcSavedEventHanler(UcEditor1_OnUcSaved);  
void UcEditor1_OnUcSaved(bool isSuccess)  
{  
    //todo:  
} 

//2.1、
public event EventHandler OnUcSaved;
//2.2、
public class SavedEventArgs: EventArgs
{
    public SavedEventArgs(bool isSuccess)
    {
this.isSuccess= isSuccess;   
    }
    public bool isSuccess;   
}//end of class SavedEventArgs
//3、  
UcEditor1(用户控件).OnUcSaved+= new EventHandler(UcEditor1_OnUcSaved);

void UcEditor1_OnUcSaved(object sender,EventArgs e)  
{  
    //todo:  
}  

btnVal0.Click += new EventHandler(but_Click);
void but_Click(object sender, EventArgs e)
{
    //todo
}
