推荐答案

很难知道从哪里开始。



如果您的Main_form没有显示，可能是因为您尝试显示它的表单是您的启动表单 - 当您关闭时，您的应用程序终止 - 所以你永远不会看到新的表单。



我会改为隐藏表单，然后在Main_form实例从ShowDialog返回后关闭它。但是我也会禁用条件顶部的计时器。



如果您要做的是显示某种形式的闪屏，然后我不会这样做 - 我会看看这个： C＃中一个非常好的启动画面 [ ^ ]

It''s difficult to know where to start really.

If your Main_form isn''t showing, it''s probably because the form you are trying to show it from is your startup form - and when you close that your application terminates - so you never get to see the new form.

I would instead Hide the form and then Close it after the Main_form instance returns from ShowDialog. But I''d disable the timer at the top of the conditional, as well.

If what you are trying to do is show a splash screen of some form, then I wouldn''t do it this way - I would have a look at this instead: A Pretty Good Splash Screen in C#[^]
