Why doesn't Clipboard.GetText work?

问题

String str = Clipboard.GetText();

throws an exception

An unhandled exception of type 'System.StackOverflowException' occurred in PresentationCore.dll

How do I prevent this problem?

回答1:

You could try:

Clipboard.GetText(System.Windows.Forms.TextDataFormat.Text)

Or take a look here: Clipboard.GetText returns null (empty string)

Look at the accepted answer in this thread:

Link to working code sample

In summary you need to ensure you start or are running in an STAThread with staThread.SetApartmentState(ApartmentState.STA); I also suggest you add a little bit of sleep or wait after join as sometimes the clipboard content is not immediately avaliable when staThread.Join() returns.
