C# 如何在VSTO Word加载项中访问KeyUp和KeyDown事件?
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

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来实现呢
