回答1:

You shuld use Clipboard class (msdn) and SelectedText property of TextBox (msdn):

To copy data to the clipboard use SetText method (msdn).

To get data from the clipboard use GetText method (msdn).

Following code copy selected text from TextBox to clipboard:

Clipboard.SetText(tbText.SelectedText);

回答2:

 Clipboard.SetText("Hello, clipboard");

To copy the contents of a textbox:

  Clipboard.SetText(txtClipboard.Text);

To get the content in Clipboard

    string  str= Clipboard.GetText()

回答3:

To set some sort of text in the clipboard:

Clipboard.SetText("Whatever you want");

So in yourcase

Clipboard.SetText(txtMyTextBox.Text);

To get it back, use

Clipboard.GetText();

txtMyTextBox.Text = Clipboard.GetText();
