C# 如何在VSTO Word加载项中访问KeyUp和KeyDown事件?_C#_Events_Ms Word_Vsto_Office Addins - Fatal编程技术网

C# 如何在VSTO Word加载项中访问KeyUp和KeyDown事件?

C# 如何在VSTO Word加载项中访问KeyUp和KeyDown事件?,c#,events,ms-word,vsto,office-addins,C#,Events,Ms Word,Vsto,Office Addins,我的问题很简单,你可以说它是重复的,但它不是这样的,因为我想在VisualStudio2015中使用C进行开发时检测VSTO Word插件中的按键事件,如KeyUp,KeyDown,并按照KeyCode运行其他功能 根据MSDN文档,VSTO插件没有此类事件,但它们提供了一些与之类似的其他事件,如Document.SelectionChange事件和ApplicationEvents 4\u事件。Windows选择更改事件,但它们不符合要求 那么,是否有任何方法可以使用C#…?,以简单的方式按照

我的问题很简单,你可以说它是重复的,但它不是这样的,因为我想在VisualStudio2015中使用C进行开发时检测VSTO Word插件中的按键事件,如
KeyUp
KeyDown
,并按照
KeyCode
运行其他功能

根据MSDN文档,VSTO插件没有此类事件,但它们提供了一些与之类似的其他事件,如
Document.SelectionChange事件
ApplicationEvents 4\u事件。Windows选择更改
事件,但它们不符合要求

那么,是否有任何方法可以使用C#…?,以简单的方式按照我的问题来实现呢

我读到的:

关于StackOverflow有许多相关问题,但没有一个与我的问题一致

我正在尝试的:

我正在尝试以下在共享的代码,此代码工作正常,但仅在Microsoft Word外部单击时捕获事件。它在键入Word时未捕获事件。我还想在事件上捕获并运行自己的函数,而不想解释自己的函数,比如键入字母等
