C# WPF Clipboard.SetText() 不能正常工作

Question

I have encountered a problem while using the Clipboard in a WPF Application: My code looks like this:

        var msg = "sample message for the clipboard";
        Clipboard.Clear();
        Clipboard.SetText(msg);

But only "\\t\\t\\t\\r\\n" gets stored in my clipboard. This is the only code that uses the Clipboard in my application and it gets called.

*Edit: Found the error. I used the above code for a copy-paste operation in a DataGridRow. This works for that:

 private void OnCopyingRowClipboardContent(object sender, DataGridRowClipboardEventArgs e)
    {
            var msg = "sample"
            e.ClipboardRowContent.Clear();
            e.ClipboardRowContent.Add(new DataGridClipboardCellContent(e.Item, (sender as DataGrid).Columns[0], msg));
    }

I guess the problem was that it automatically tried to copy sth out of my DataGrid after my Clipboard.SetText(..) and overwrote my text again.

Answer 1

Clearing the Clipboard is redundant as SetText does that automatically for you.

This is what I usually use:

Clipboard.SetText(msg, TextDataFormat.Text);

or

Clipboard.SetText(msg,TextDataFormat.UnicodeText);

Answer 2

    protected void clipboardSetText(string inTextToCopy)
    {
        var clipboardThread = new Thread(() => clipBoardThreadWorker(inTextToCopy));
        clipboardThread.SetApartmentState(ApartmentState.STA);
        clipboardThread.IsBackground = false;
        clipboardThread.Start();
    }
    private void clipBoardThreadWorker(string inTextToCopy)
    {
        System.Windows.Clipboard.SetText(inTextToCopy);
    }
