推荐答案

看看使用Eventhandler处理关闭事件(如此处 [^ ]). Have a look at using an Eventhandler for the close event (as described here[^]).

句柄 FormClosed [ ^ ]事件. 在您的代码中，您可以执行以下操作: Handle FormClosed[^] event. In your code, you can do something like this: LoginForm loginForm = new LoginForm(); loginForm.FormClosed += new FormClosedEventHandler(this.LoginForm_FormClosed); ... void LoginForm_FormClosed(object sender, FormClosedEventArgs e) { MessageBox.Show("LoginForm has closed, with reason: " + e.CloseReason); }

让我们的方法符合逻辑.如果只有两种形式，并且您想同时关闭这两种形式，则意味着您要退出该应用程序.现在，其中一种形式是主要形式.它在调用Application.Run时定义.用作参数的形式成为主要形式.如果您关闭主窗体应用程序，则仍然存在.您只需要注意第二种形式. 覆盖其虚拟OnFormClosed方法: Let''s approach logically. If there are only two forms, and you want to close both, it means you want to exit the application. Now, one of the forms is a main one; it it defined when Application.Run is called. The form used as an argument becomes main. If you close a main form application exist anyway. You only need to take care about your second form. Overrides its virtual OnFormClosed method: //only for non-main form: protected override void OnFormClosed(FormClosedEventArgs e) { Application.Exit(); }
