.net中Membership.CreateUser自带的类和方法，将数据插入哪里去了？

//建企业账号
MembershipUser pmu = Membership.GetUser(partnerId);
if (pmu == null)
{
MembershipCreateStatus mstatus = new MembershipCreateStatus();
pmu = Membership.CreateUser(partnerId, "123456", "defaultEmail", "1", "1", false, out mstatus);
}

数据库中的aspnet_user表和aspnet_membership表
