我不相信，而且有充分的理由！您确定要禁用“取消”按钮吗？由于这是一个模式对话框，这将阻止用户继续（从而使您的应用程序无法使用），直到他们选择一个文件 - 几乎肯定会出现这种情况根本不可能的情况，或者用户不这样做想要强制保存文件。
当然，我可能是错的，并且可能存在我不知道的完全合法的情况 - 但是我担心 Microsoft 也没有意识到这种情况，因此 OpenFileDialog 不支持禁用取消按钮。
恐怕如果您真的不想要取消按钮，您将需要创建自己的对话框克隆。
I don't believe so, and with good reason! Are you sure that you want to disable the Cancel button? Being that this is a modal dialog this would prevent the user from continuing (and hence making your application unusable) until they selected a file - there are almost certainly going to be scenarios where this simply isn't possible, or the user doesn't want to be forced into saving a file.
Of course I could be wrong and there could be a completely legit scenario that I'm not aware of - however I'm afraid that Microsoft were also unaware of this scenario and so the OpenFileDialog doesn't support disabling the cancel button.
I'm afraid that if you really don't want a cancel button you will need to create your own clone of the dialog.
如果需要的话，可以循环处理取消吗？可能会让用户感到沮丧;)
handle the cancel in a loop if you want? might frustrate users ;)
