Answer 1

尝试这个

var skata = from ordtls in Tbl_OrderDetails 
             orderby (int)ordtls.Month, (int)ordtls.Year 
             select new {ordtls.Month,ordtls.Year}

或者

 var skata = from ordtls in Tbl_OrderDetails 
             orderby Convert.ToInt32(ordtls.Month), Convert.ToInt32(ordtls.Year) 
             select new {ordtls.Month,ordtls.Year}
