这是会员表，我找到了解决方案。这是：

 sqlcmd = new SqlCommand("SELECT RoleId FROM  aspnet_Roles where RoleName=@RoleName", sqlconn);
                        sqlcmd.Parameters.AddWithValue("@RoleName", "Reviewer");

                        sqlconn.Open();
                        System.Guid RoleId = ((System.Guid)sqlcmd.ExecuteScalar());

                        sqlcmd = new SqlCommand("SELECT UserId FROM  aspnet_Users where UserName=@UserName", sqlconn);
                        sqlcmd.Parameters.AddWithValue("@UserName", EditorUserName);
                        System.Guid UserId = ((System.Guid)sqlcmd.ExecuteScalar());

                        sqlcmd = new SqlCommand("SELECT RoleId FROM  aspnet_Roles where RoleName=@RoleName", sqlconn);
                        sqlcmd.Parameters.AddWithValue("@RoleName", "ReviewerEditor");
                        System.Guid ReviewerEditorRoleId = ((System.Guid)sqlcmd.ExecuteScalar());

                        sqlconn.Close();

                        ///  ///////////////////////////////////////////////////////////////////////////////////////////////////////////////

                        sqlcmd = new SqlCommand("UPDATE  aspnet_UsersInRoles SET RoleId = @RoleId WHERE (UserId= @UserId)", sqlconn);
                        sqlcmd.Parameters.AddWithValue("@RoleId", ReviewerEditorRoleId);
                        sqlcmd.Parameters.AddWithValue("@UserId", UserId);
                        sqlconn.Open();
                        sqlcmd.ExecuteNonQuery();
                        sqlconn.Close();

更新查询更正
