我已经阅读了一些有关此的主题,但是我仍然不知道如何解决此问题.我来自Java,大部分是C#的新手
我想在动画结束时附加侦听器:
myStoryBoard.Completed += new EventHandler(onMyStoryBoardCompleted);并且:
private void onMyStoryBoardCompleted(object sender, EventArgs e) { }我得到标题中的错误.我试过了:
myStoryBoard.Completed += new EventHandler<object>(onMyStoryBoardCompleted);但是我得到:
no overload for 'onMyStoryBoardCompleted' matches delegate 'System.EventHandler<object>'因此,签名似乎与EventHandler <object>不兼容,我找不到如何使其兼容的方式,我也不知道这种方法是否正确.
我读
了解C#中的事件和事件处理程序

但是仍然找不到这种情况的解决方案.
谢谢.
解决方案尝试:
private void onMyStoryBoardCompleted(object sender, object e) { }并使用通用EventHandler<object>订阅:
myStoryBoard.Completed += new EventHandler<object>(onMyStoryBoardCompleted);当然,这违反了.NET Framework约定,事件处理程序的第二个参数应为EventArgs的实例(或其派生类).我假设您正在另一个框架上运行,例如Windows 8 Metro,该框架的Timeline类定义了EventHandler<object>签名的.ui.xaml.media.animation.timelinepleted> Completed 事件.
I have read already a few threads about this, but I still don't know how to solve it in my case. I come from Java and mostly new to C#
I want to attach listener when animation finishes:
myStoryBoard.Completed += new EventHandler(onMyStoryBoardCompleted);And:
private void onMyStoryBoardCompleted(object sender, EventArgs e) { }And I get the error in the title. I tried:
myStoryBoard.Completed += new EventHandler<object>(onMyStoryBoardCompleted);But then I get:
no overload for 'onMyStoryBoardCompleted' matches delegate 'System.EventHandler<object>'So it seems that the signature is not compatible with EventHandler<object> and I couldn't find how to make it compatible, I also don't know if this approach is correct.
I read
Understanding events and event handlers in C#
C# Dynamic template implicit conversion error from System.EventHandler to System.EventHandler<TEventArgs>
defining event handler for Tick event of DispatcherTimer in windows 8 app
But still don't find the solution for this case.
Thanks in advance.
解决方案Try:
private void onMyStoryBoardCompleted(object sender, object e) { }And subscribe using the generic EventHandler<object>:
myStoryBoard.Completed += new EventHandler<object>(onMyStoryBoardCompleted);Of course, this goes against the .NET Framework convention that the second argument to an event handler should be an instance of EventArgs (or a class derived thereof). I am assuming that you are running on another framework, such as Windows 8 Metro, whose Timeline class defines a Completed event with an EventHandler<object> signature.
