推荐答案

您可以使用以下方式关闭应用程序.

Hi,

You can close the application using the following way.

private void frmMainMDI_FormClosing(Object sender, FormClosingEventArgs e)
       {
          Application.Exit();

       }

这取决于您的操作方式.
如果要通过Main方法打开登录表单，并在成功登录后隐藏登录表单并显示主表单，则取决于您如何显示它:

如果您使用ShowDialog，则只需在ShowDialog调用之后立即在登录表单中添加一个Close.
如果使用的是Show，则将处理程序添加到主窗体FormClosed事件中，然后从此处调用Close.

如果您正在做其他事情，那么我们需要知道什么，因为我们看不到您的屏幕，无法访问您的HDD或无法读懂您的想法.我们只能与您所说的一起工作！ :laugh:

It depends on how you are doing this.
If you are opening the login form from the Main method, and on sucessfull login you are hiding the login form and showing the main form, then it depends on how you are showing it:

If you use ShowDialog, then just add a Close to the login form immediately after the ShowDialog call.
If you are using Show, then add a handler to the main form FormClosed event and call Close from there.

If you are doing something else, then we need to know what, as we can''t see your screen, access your HDD, or read your mind. We can only work with what you tell us! :laugh:
