推荐答案

您只需在打开表格的代码中添加一张支票，以确保允许用户使用。



有两个地方可以做到这一点：当您调用Show以显示表单时，或者在Form.Load事件中（您只需检查，然后如果不允许用户，请调用Close方法）。

前者是更安全，但后者更容易确保允许访问 - 您无需记住在打开表单的任何地方进行检查。

All you have to do is add a check in the code where you are opening the form to ensure the user is permitted.

There are two places you can do this: When you call Show to display the form, or in the Form.Load event (all you have to do is check, then if the user is not permitted, call the Close method).
The former is "safer" but the later is easier to ensure that access is permitted - you don't need to remember to check everywhere you open the form.
