我正在UserControl使用动态创建许多 sLoadControl(String)并希望订阅它们中的每一个的事件。

我所有的控件都继承了一个Interface需要实现 common 的 common Event：

public interface IObjectProcessor
{
    event EventHandler<ObjectProcessedEventArgs> ObjectProcessed;
}

所以我在我的页面加载事件中执行下一步：

protected void Page_Load()
{
   switch(Request["type"])
   {
     case "user":
     {
        LoadControl("AddUser.ascx", delegate(object sender, ObjectProcessedEventArgs e)
        {
           // do something
        });
        break;
     }
   }
}

private void LoadControl(string path, Action<object, ObjectProcessedEventArgs> action)
{
    var control = (IObjectProcessor)LoadControl(path)
    control.ObjectProcessed // here!
}

如何订阅代表参加此活动？

更改Action<object, ObjectProcessedEventArgs>为EventHandler<ObjectProcessedEventArgs>：

private void LoadControl(string path, EventHandler<ObjectProcessedEventArgs> handler)
{
        var control = (IObjectProcessor)LoadControl(path)
        control.ObjectProcessed += handler;
}
