注解

UpdateUser 采用作为输入,使用成员资格用户的当前信息填充 MembershipUser 对象,并使用 MembershipUser 对象的属性值更新数据源。UpdateUser takes, as input, a MembershipUser object populated with current information for the membership user and updates the data source with the property values of the MembershipUser object. 您可以使用 GetUserGetAllUsersFindUsersByNameFindUsersByEmail 方法,在数据源中构造新的 MembershipUser,或检索用当前值填充的 MembershipUser 对象。You can construct a new MembershipUser, or retrieve a MembershipUser object populated with current values at the data source using the GetUser, GetAllUsers, FindUsersByName, or FindUsersByEmail methods.
