Not sure if you want to know if they are a "registered" user or have logged in (as the Login status would indicate)
不确定您是否想知道他们是“注册”用户还是已登录（如登录状态所示）
Here's to know if they are logged in (what the Login status uses):
这是要知道他们是否已登录（登录状态使用什么）：
System.Web.HttpContext.Current.User.Identity.IsAuthenticated;
回答by Rex M
MembershipProvider.GetUser(string username, bool updateLastActivityDateTime)
This will get you the user, or return null of the user does not exist (has not been registered)
这将获得您的用户，或返回用户不存在的空值（尚未注册）
