推荐答案

当您关闭在中打开的第一个表单时主方法（在Program.cs中）通过 Application.Run 它存在Run方法并返回Main - 然后退出并终止应用程序，释放它使用的所有资源 - 这也意味着关闭它打开的所有窗口。你不能阻止这种情况，你也不应该这样做，因为如果你不这样做那么就没有办法关闭整个应用程序并清除内存。



我建议处理Form.FormClosing事件（或类似事件），它允许你闪现你确定要关闭这个应用程序吗？对话框，如果用户不想使用EventArgs的Cancel属性取消表单关闭，则不会退出应用程序。

When you close the first form that is opened in the Main method (in Program.cs) via Application.Run it exist the Run method and returns to Main - which then exits and that terminates the application, releasing all resources it used - which also means closing all windows it has open. You can't prevent that, and neither should you want to because if you don't do that then there is no way to shut down the whole app and clear it out of memory.

What I'd suggest to handling the Form.FormClosing event (or similar) which allows you to flash up a "Are you sure you want to close this app?" dialog and if the user doesn't want to using the Cancel property of the EventArgs to cancel the form closure an thuis not exit the app.
