Remarks

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. 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.
