C# 按降序查询组的前两个元素

我有一张这样的桌子：

FruitID | FruitDate | FruitType
  23    |  10/20/14 |   3
  32    |  10/12/14 |   3
  39    |  09/23/14 |   3

有许多

水果类型

，我想提取一个包含最后两个水果的对象模型列表，例如

{groutid:23，Date:10/20}，{groutid:32，Date:10/12}

这就是我所拥有的：

var Output = (from f in MyDC.Fruits
              where ... some condition
              orderby f.FruitDate descending
              group f by f.FruitType in FruitGroups
              select.... new FruitModel()
              {
                   FruitID = ...
                   FruitDate = ...
                   FruitType = ...

              }).ToList();

我很难接受最新的2。如何获取每个

水果类型的最后两个
的列表

var Output = (from f in MyDC.Fruits
              where ... some condition
              orderby f.FruitDate descending
              group f by f.FruitType in FruitGroups
              select.... new FruitModel()
              {
                   FruitID = ...
                   FruitDate = ...
                   FruitType = ...

              }).Take(2).ToList();

后续编辑

在
子句中添加缺少的
；以下是查询：

var Output = (from f in MyDC.Fruits
              where ... some condition
              orderby f.FruitDate descending
              group f by f.FruitType in FruitGroups
              from t in FruitGroups
              select new FruitModel()
              {
                   FruitID = t.FruitID,
                   FruitDate = t.FruitDate
                   FruitType = t.FruitType

              }).Take(2).ToList();

试试这个：-

var query = from fruit in fruitsData
                        group fruit by fruit.FruitType into g
                        select new
                        {
                            FruitType = g.Key,
                            Fruits = g.OrderByDescending(x => x.FruitDate).Take(2)
                        };

工作。
好的，这让我开始了；仍然需要在select之前添加一个新from子句。做了编辑。但是谢谢！！这就是答案！如果回答了您的问题，请将此标记为答案：）如果您有任何其他问题，请询问
