如何监视 C# 中的剪贴板更改? [英] How do I monitor clipboard changes in C#?

问题描述

是否有我可以通过 C# 访问的剪贴板更改或更新事件?

Is there a clipboard changed or updated event that i can access through C#?

推荐答案

我认为你必须使用一些 p/invoke:

I think you'll have to use some p/invoke:

[DllImport("User32.dll", CharSet=CharSet.Auto)]
public static extern IntPtr SetClipboardViewer(IntPtr hWndNewViewer);

参见这篇文章如何在c#中设置剪贴板监视器

基本上，您使用

_ClipboardViewerNext = SetClipboardViewer(this.Handle);

然后您将收到 WM_DRAWCLIPBOARD 消息，您可以通过覆盖 WndProc 来处理该消息:

and then you will recieve the WM_DRAWCLIPBOARD message, which you can handle by overriding WndProc:

protected override void WndProc(ref Message m)
{
    switch ((Win32.Msgs)m.Msg)
    {
        case Win32.Msgs.WM_DRAWCLIPBOARD:
        // Handle clipboard changed
        break;
        // ... 
   }
}

(还有更多工作要做；沿剪贴板链传递内容并取消注册您的视图，但您可以从 文章)

(There's more to be done; passing things along the clipboard chain and unregistering your view, but you can get that from the article)
