推荐答案

基于公认的设计，在Winforms中解决此类问题的步骤:
1.具有主要形式-形式A.始终保持活动状态.
2.由于您需要登录，因此创建一个子窗体-窗体B.在窗体A上方显示它.
3.如果用户提供正确的凭据，请根据需要隐藏/关闭表单B并使用UI显示表单A
4.如果用户提供了错误的凭据，请显示错误

这样，您就不会出现登录表单的打开/关闭问题.此外，您必须在Winforms中知道，不能关闭父窗口并保持子窗口处于打开状态-因此上述设计将检查所有内容而不会出现问题.

Steps for such scenarios in Winforms, based on good accepted design:
1. Have a main form - form A. Always keep it active.
2. Since you need login, create a child form - form B. Show it above form A.
3. If user provides correct credentials, hide/close form B and show form A with UI as per need
4. If user provides wrong credentials, show error

This way, you don''t have issue with opening/closing issue with login form. Further, as you must be knowing in Winforms, parent window cannot be closed keeping child window open - thus the above said design would keep everything in check without issues.
