如何将选定的文本复制到剪贴板 [英] How to copy selected text to the clipboard

问题描述

你好.我有个问题.我需要复制在任何应用程序(无论是Web浏览器还是记事本)中选择的文本，并将其复制到剪贴板.

Hello. I have a problem. I need to copy the text selected in any application (whether web-browser or notepad) and copy it to the clipboard. Who than can help please!

推荐答案

在没有一些p/invoke的情况下，这在C#中是无法完成的.您需要使用Win32 API调用来查找焦点窗口并向其询问文本.

That can''t be done in C# without some p/invoke. You need to use Win32 API calls to find the focused window and ask it for it''s text.

此问题仅对以下情况有意义:将任何应用程序中的操作复制到C#应用程序中，然后使用剪贴板中的内容.

我能想到的解决方案的唯一方法是实现GlobalSystemHook:请参见George Mamaladze [

This question makes sense to me only if: you are going to return focus after a copy operation in any application to your C# application, and then use the clipboard contents.

The only way I can imagine a solution is by implementing a GlobalSystemHook: see "Processing Global Mouse and Keyboard Hooks in C#" by George Mamaladze[^] which will notify/invoke your C# application in the case of a control-c event.

When notified of that event, you will, then, have to examine the clipboard contents to filter for text-only content ... I assume.

作为使用Windows notepad.exe的替代方法您是否考虑过将记事本克隆嵌入到您的应用程序中.为此，我在C#中创建了记事本的精确副本.您可以在此处找到源代码:

As an alternative to using windows notepad.exe have you considered embedding a notepad clone into your application. I created an exact clone of notepad in C# for exactly this purpose. You can find the source code here:
