推荐答案

基本上，您需要调用 Application.Run 来处理窗口的消息.

Basically, you need to call Application.Run in order to process the window's messages.

如果表单之一是主窗口"，即您希望在窗口关闭时退出应用程序，则应使用 Application.Run(form).

If one of the forms is your "main window", i.e. you want the application to exit when the window closes, you should use Application.Run(form).

如果您希望多个窗口中没有一个特别重要，请仅使用 Application.Run()，然后通过调用 Application.Exit().

If you want several windows with none of them being especially significant, use just Application.Run(), and decide on your own when to exit the application by calling Application.Exit().

另一种替代方法是在第二个表单上调用 Form.ShowDialog . ShowDialog 有其自己的消息泵，因此在打开第二个窗口时，将同时处理两个窗口的消息.但是在这种情况下，当您调用 ShowDialog 的窗口关闭时，另一个窗口将被冻结.

Another alternative is to call Form.ShowDialog on the second form. ShowDialog has its own message pump so while the second window is open, messages will be processed for both windows. But in this scenario, when the window on which you called ShowDialog is closed, the other window will be frozen.
