问题
Is there a way to get the clipboard on a Mac in Mono that doesn't return an empty string? This is using the latest NON-beta version of mono.
Clipboard.SetText(String) works fine and I can paste to other programs.
Clipboard.GetText(TextDataFormat.UnicodeText)
Clipboard.GetText(TextDataFormat.Text)
Clipboard.GetText(TextDataFormat.Rtf)
All return "" even though Clipboard.ContainsText(TextDataFormat.UnicodeText) returns true.
EDIT:
The solution ended up being to use NSPasteboard on mac. https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ApplicationKit/Classes/NSPasteboard_Class/Reference/Reference.html
回答1:
It may be that mono is interpreting TextDataFormat.UnicodeText to mean utf-16 but the 'other application' is placing the text on the clipboard as utf-8.
The following is a patch that, if I remember correctly, fixed an issue similar to this.
clipboard patch
You will need to build mono from and apply the patch to try this out.

I could not ever get Clipboard to return anything. Mono has wrappers around NSPasteboard so it ended up being pretty easy this way.
