WPF 自定义事件参数

自定义事件参数类:

/// <summary>
/// 自定义事件参数类
/// </summary>
public class MyRoutedEventArge:RoutedEventArgs
{}

自定义路由事件:

//自定义事件委托
public delegate void MyRoutedEventHandler(object sender ,MyRoutedEventArge e);

//路由事件
public static readonly RoutedEvent MyRoutedEvent = EventManager.RegisterRoutedEvent(
   "MyRouted", RoutingStrategy.Bubble, typeof(MyRoutedEventHandler), typeof(UserControl1));

public event MyRoutedEventHandler MyRouted
{
    add { AddHandler(MyRoutedEvent,value); }
    remove { RemoveHandler(MyRoutedEvent,value); }
}

 

引发事件:

 

MyRoutedEventArge args = new MyRoutedEventArge();
args.RoutedEvent = MyRoutedEvent;
RaiseEvent(args);
