如何调用/调用按钮单击事件处理程序形成另一个处理程序？ （C＃ ） [英] How Do I invoke/call a button click event handler form another handler? (c# )

问题描述

在一个按钮的事件处理程序中，单击我然后再重新使用另一个事件处理程序/点击。然而，我似乎无法弄清楚如何做到这一点。

可能引起麻烦的一点是，我要点燃的第二个项目的处理程序不是在同一个表单/上下文。

似乎我应该可以调用方法...

但我似乎无法做到这一点。

这是在紧凑框架/ Win Mobile

解决方案

您需要执行以下操作之一：

• 提供访问权限处理程序包含类实例（即对该对象的引用）


• 使处理程序成为静态，所以任何实例都可以直接引用它。


• 将处理程序在一些其他全球可用的对象（静态，单例等）中，所以两个消费者都可以使用它


• 使用提供事件聚合的框架，所以你不必担心这样的事情。 li>
  

I must be missing something obvious - I am new to .NET - been developing in C++/MFC for years.

In an event handler for a button click I would like to then re-use another event handler/click. However, I can't seem to figure out how to do that.

The bit that may be causing trouble is that the handler for the second item I want to "fire" is not on the same form/context.

It seems that I should just be able to call the method...

But I don't seem to be able to do it.

This is in compact framework/Win Mobile

解决方案

You need to do one of the following:

• Provide access to the handler's containing class instance (i.e. a reference to that object)
• Make the handler a static so any instance can reference it directly
• Put the handler in some other globally available object (static, singleton, etc) so both consumers can use it
• Use a framework that provides event aggregation so you don't have to worry about such things
