asp.net mvc - Get LAST_INSERT_ID from transaction -

-

i have following code:

                using (mysqlconnection connection = new mysqlconnection(this.connectionstring))                 {                     connection.open();                     using (mysqltransaction transaction = connection.begintransaction())                     {                         var r = connection.execute(@"insert tablea (`listid`, `parentlistid`, `name`, `userid`)                             values                             (null, @parentlistid, @name, @userid);                              insert `tablea_misc` (`listid`, `userid`, `permissions`)                             values                             (last_insert_id(), @ownerid, 'read');                              select cast(last_insert_id() unsigned integer);",                         new {                             parentlistid = _parentlistid,                             name = _name,                             userid = _currentuser.user_id                         }, transaction);                         transaction.commit();                     }                 }

how can retrieve the last_insert_id() since r returns number of rows inserted?

thank you

changing fixed:

 using (mysqlconnection connection = new mysqlconnection(this.connectionstring))                 {                     connection.open();                     using (mysqltransaction transaction = connection.begintransaction())                     {                         var lastid = connection.query<int>(@"insert tablea (`listid`, `parentlistid`, `name`, `userid`)                             values                             (null, @parentlistid, @name, @userid);                              insert `tablea_misc` (`listid`, `userid`, `permissions`)                             values                             (last_insert_id(), @ownerid, 'read');                              select cast(last_insert_id() unsigned integer);",                         new {                             parentlistid = _parentlistid,                             name = _name,                             userid = _currentuser.user_id                         }, transaction);                         transaction.commit();                     }             }
