NHibernate 查詢多表返回到IList<Model>中

public IList<TodoListGridData> QueryTodoList(string department)
        {
            IList queryResult = this.TradeMeetingDao.GetITradeMeetingGrid(department);

            IList<TodoListGridData> gridData =
                (from c in queryResult.OfType<object[]>()
                 let _Oid = Convert.ToString(c[0])
                 let _ModifyDate = Convert.ToString(c[1])
                 let _NameEn = Convert.ToString(c[2])
                 let _NameLocal = Convert.ToString(c[3])
                 let _Status = Convert.ToString(c[4])
                 let _Note = Convert
.ToString(c[5])
                 select new TodoListGridData
                 {
                     Oid = _Oid,
