You can use the built in method for this purpose.
为此，您可以使用内置方法。
textBoxResults.SelectAll();
textBoxResults.Focus(); //you need to call this to show selection if it doesn't has focus

This method enables you to select all text within the control.
此方法使您可以选择控件内的所有文本。
public void CopyAllMyText()
{
// Determine if any text is selected in the TextBox control.
if(textBox1.SelectionLength == 0)
// Select all text in the text box.
textBox1.SelectAll();
// Copy the contents of the control to the Clipboard.
textBox1.Copy();
}
