OpenClipboard失败时复制粘贴从WPF DataGrid中的数据 [英] OpenClipboard Failed when copy pasting data from wpf DataGrid

问题描述

我有数据网格使用一个WPF应用程序。直到我安装VS2012的应用程序正常工作和Blend + SketchFlow的预览。现在，当我试图将数据从网格复制到按Ctrl + C（在任何应用程序）的剪贴板中，我得到以下异常：

I've got a WPF app using datagrid. The app worked fine until I installed VS2012 and Blend+SketchFlow preview. Now, when I'm trying to copy the data from the grid into the clipboard with ctrl+C (in any app), I'm getting following exception:

这实在是烦人。

我已经看到了一些引用这个问题的此处并在网络上的不同位置，没有真正解决问题。

I've seen some references to this problem here and on various locations on the web, with no real solution.

我可以验证剪贴板被锁定时，此异常在Visual Studio是提高了，因为我不能复制粘贴消息（必须将其写入到文件）。此外，在复制过程开始前剪贴板没有上锁。

I can verify that the clipboard is locked when this exception is raised in visual studio, as I couldn't copy paste the message (had to write it to a file). Also, the clipboard wasn't locked before the copy process started.

要是有人在这里有这个问题，并解决它？

Had anybody here have this problem and solved it?

推荐答案

我们使用的是.NET 4.0。我们有同样的问题，但注销系统后，用代码来了一段做工精细。
终于找到了替代品。

We are using .NET 4.0. We had the same problem but after logging off the system, code used to work fine for sometime. Finally found the alternative.

如果要复制剪贴板一个字符串

If you want to copy a string on clipboard

string data = "Copy This"

到现在我用下面的方法

Clipboard.SetText(data);

这一次又一次失败。然后我看着在 http://msdn.microsoft可设置在剪贴板中的文本的其他方法.COM / EN-IN /库/ system.windows.clipboard.aspx
和尝试以下

It was failing again and again. Then I looked at other methods available to set text in clipboard at http://msdn.microsoft.com/en-IN/library/system.windows.clipboard.aspx and tried following

Clipboard.SetDataObject(data);

和它的工作:)。永远不会再有问题。

and IT worked :). Never had issue again.
