我有一个模态表单 ShowDialog 我想关闭表单，如果 1 按下按钮有效2 如果静态变量中的值发生变化无效

问题描述

我有一个 Modal ShowDialog 表单。尝试关闭创建的表单，如果发生以下两件事之一按下表单上的 1 个按钮或 2 静态变量中的值发生变化。到目前为止，该按钮有效，我可以使用另一个按钮来检查值的状态并查看更改?如何让第二部分关闭表单？

Main_Menu.cs
  public void OverloadTripearly()
    {
        
        OverloadTripEarly overloadTripEarly = new OverloadTripEarly();
        overloadTripEarly.Owner = this;
        overloadTripEarly.ShowDialog();             
      //  overloadTripEarly.Refresh();
     //   OLTrip = overloadTripEarly; // assign object to enter
    }
