基于在ASP.NET中使用它来获取有关当前经过身份验证的用户的登录信息，我看到了一些可行的方法。首先，如果您使用Active Directory成员资格提供程序进行Forms身份验证，则可以在那里捕获用户名。然后你只需将用户名放在GetUser()方法中，如下所示：GetUser(yourUser)，你应该得到所需的信息。

如果这不是一个选项，我相信用户名信息存储在您的登录控件下（在您的情况下，如果您确实使用登录控件，我相信名称为user_login）。您只需说出user_login.username并将其放在GetUser()方法中。

最后，您可以尝试HttpContext.Current.User.Identity.Name的旧回退并将其放在GetUser()方法中。
