只需关闭模式对话框.它不会像普通的Form实例那样处理，因此您只需将其DialogResult属性设置回None并再次调用ShowDialog()即可使其恢复活动.

Just close the modal dialog. It doesn't get disposed like normal Form instances do so you simply bring it back alive by setting its DialogResult property back to None and calling ShowDialog() again.

请注意，在模式对话框中调用Hide()也会将其关闭，因为您的应用程序的所有窗口均已禁用，所以一定要关闭它.与Close()没什么不同.

Note that calling Hide() on a modal dialog also closes it, necessarily so since all of your app's windows are disabled. No different from Close().
