SQL语句转成Linq，高手帮忙

select sum(UserConsumeMoney) as totalMoney, convert(nvarchar(7), ConsumeDay,120) 
as monthConsume from T_UserConsumeDay
group by convert(nvarchar(7), ConsumeDay,120)

var query=from t in T_UserConsumeDay
          group t by t.ConsumeDay.ToString("yyyy-MM") into g
          orderby g.Key
          select new 
          { 
              totalMoney=g.Sum(m=>m.UserConsumeMoney),
              monthConsume=g.Key
          };
