我发现，当我点击NumericUpDown控件，然后在案例2中按tab键时：在控件的键关闭事件中，我将原始源代码作为文本框

**   private void Control_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.OriginalSource as Control != null
            && e.Key == Key.Tab)
        {
            Int32 index = (e.OriginalSource as Control).TabIndex;
            if (index == Int32.MaxValue) index = index1; //??//
            if (Keyboard.Modifiers == ModifierKeys.None)
            {

            }
            else if (Keyboard.Modifiers == ModifierKeys.Shift)
            {

            }
        }
