推荐答案

你不能开火 （调用）任何地方的任何事件，除了声明事件的类型，甚至在派生类中。这是一个重要的限制（与常规委托实例相比），这使事件变得如此安全和有价值。如果单击事件，当用户实际点击物理鼠标时将触发该事件。如果可以模拟，但在较低级别，通过原始Windows API SendInput ， http://msdn.microsoft.com/en-us/library/windows/desktop/ms646310%28v=vs.85%29.aspx [ ^ ]， http://www.pinvoke.net/default.aspx/user32。 sendinput [ ^ ]。 我认为你不想要它。



事情是：我确定你不要实际上需要来开火和事件。您只需要具有与调用事件时相同的效果。这将是一个不同的故事，更合理的事情。执行以下操作：



仅向所需单击事件的调用列表添加一个处理程序。在此处理程序中，调用一些单独的函数;这应该是事件处理程序中唯一的语句。并在其他地方写一个对此函数的调用，在那里你要模拟点击。就这么简单。

You cannot "fire" (invoke) any event anywhere, except the type where the event is declared, not even in a derived class. This is important limitation (compared to "regular" delegate instances), which makes events so safe and valuable. In case of the Click event, it will be fired when a user actually clicks with a physical mouse. If could be simulated, but on a low level, via raw Windows API SendInput, http://msdn.microsoft.com/en-us/library/windows/desktop/ms646310%28v=vs.85%29.aspx[^], http://www.pinvoke.net/default.aspx/user32.sendinput[^]. I don''t think you want it.

The thing is: I''m sure you don''t actually need to "fire" and event. You just need to have the same effect as you would have when the event is invoked. This would be a different story, much more reasonable thing. Do the following:

Add only one handler to the invocation list of the required Click event. In this handler, call some separate function; this should be the only statement in your event handler. And write a call to this function elsewhere, where you wanted to simulate the click. As simple as that.
