转换SQL被分LINQ组，算

如何转换SQL到LINQ转换SQL被分LINQ组，算

SELECT 
      [good_id] 
      ,MIN([good_price]) as minPrice 
      ,Count([distributor_id]) as distrCount 
     FROM [Provizor].[dbo].[PRICES] where region_id=22 
     GROUP BY [good_id] 
     ORDER BY distrCount desc

如何做到这一点的LINQ分组

事情是这样的：

var query = dbo.Prices 
       .Where(x => x.region_id == 22) 
       .GroupBy(x => x.good_id) 
       .Select(g => new 
       { 
        minPrice = g.Min(x => x.good_price), 
        distrCount = g.Count(x=> x.distributor_id!=null) 
       } 
       .OrderByDescending(x => x.distrCount);

LINQ var price =（从_db.PRICE的其中p.region_id == 22 群p由p.good_id成克选择新的{ good_id = g.Key ，minPrice = g.Min（X => x.good_price），distrCount = g.Count（X = > x.distributor_id！= null） } ）.OrderByDescending（x => x.distrCount）; – Sergey 2012-04-28 05:07:27
