剪贴板功能 [英] ClipBoard Functionality

问题描述

新年快乐.

我能够实现剪贴板功能，但我的疑问是我们无法从内容的复制位置得知.

场景:

1.我正在运行剪贴板应用程序.
2.打开记事本并复制一些内容.
3.我可以粘贴内容.

在这里，我要粘贴内容，如果是记事本，也要显示从记事本复制的内容；如果是从MS Word复制过来的，则要显示MS Word.

推荐答案

检查是否有办法让剪贴板拥有者.

例如参见此线程 [ ^ ].它不在C#中，但可能会让您了解我要说的话.

Check if there is a way to get the clip board owner.

For e.g. see this thread[^]. Its not in C#, but it might give you an idea of what I''m trying to say.
