如何在SQL表中引用成员资格提供者用户？

Question

当我创建SQL表并且我想在ASP.NET中引用成员资格提供程序用户时，我使用什么类型的字段以及如何从用户那里获取值？

在SQL Server中，您将使用UNIQUEIDENTIFIER作为列类型并将其映射到 [dbo]。[aspnet_Users]。[UserId] 。假设您在ASP.Net应用程序中使用默认的SqlMembership。要在C＃中获取登录用户的UserId，您可以使用：

MembershipUser mu = Membership.GetUser();  // This gets the CURRENTLY logged in user.
MembershipUser mu = Membership.GetUser("username");  // This gets the user with username username.
// Obviously you'd use only one of the above 2 lines, otherwise you'd get an error about mu being declared twice.
Guid currentUserId = (Guid)mu.ProviderUserKey;
