注解

对于新用户， LastLoginDate 如果用户尚未登录，则 等于 CreationDate 。 如果成功调用 方法，则会 LastLoginDate 更新为 ValidateUser 当前日期和时间。

还可以通过设置 LastLoginDate 的 属性 MembershipUser 并将修改后 MembershipUser 的对象传递给 方法来 UpdateUser 修改上次登录日期。

将 SqlMembershipProvider 、LastLoginDate、 LastActivityDate和 LastPasswordChangedDate 日期设置为CreationDate通过 CreateUser 方法创建成员身份用户的相同日期和时间。
