WPF给控件添加粘贴事件 （Ctrl+V）

private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            //控件名称
            //事件名称
            DataObject.AddPastingHandler(textBox2, TextBoxPlus_PastingEvent);
        }

 private void TextBoxPlus_PastingEvent(object sender, DataObjectPastingEventArgs e)
        {
            if (e.DataObject.GetDataPresent(typeof(String)))
            {
                String pastingText = (String)e.DataObject.GetData(typeof(String));
                e.CancelCommand();
            }
            
            
        }
