Revit Addin 在窗体关闭时运行
Revit Addin Runs When Form is Closed
我在 Revit 中的程序有两个列表框，根据选择的内容，它会对图元进行更改。但是，我发现如果用户选择了一些选项然后关闭了表单，它仍然会 运行 选择选项。我的代码如下。我尝试根据我在网上找到的内容添加一个 Form_Closing 方法，但我的执行方法 运行 一直到 none-the-less。
我在执行方法中有一个 if 语句应该 return Result.Cancelled 并且应该停止程序。感觉跟我的Form_Closing方法的事件有关系。感谢您的帮助。

//some methods used are not shown as they are only used in the execute method
Execute 方法将在 GUI 线程之外的另一个线程上调用 - while 循环将看不到更新...您需要想办法两个线程互相发信号。
甚至更好：设置一个 ExternalEvent 处理程序而不是 while 循环，并将 while 循环的主体用作事件处理程序的主体。在 Execute 方法中启动处理程序，并在 window get 关闭时停止它。
