C# LINQ GroupBy列表根据字典中的键在字典中在列表C中

我正在创建一个列表，其中包含用于从wcf服务创建Json的字典

我是这样创作的：

List<Dictionary<string, Dictionary<string, Object>>> superduperList = new List<Dictionary<string, Dictionary<string, Object>>>();

[
{
DepartureJ: {},
ReturnJ: {},
pricesDepartureJ: {},
pricesReturnJ: {},
DepartureSegmentsJ: {},
ArrivalSegmentsJ: {}
},
...,
...,
...,
...,
...,
]

   "DepartureJ": {
        ArrivalDateTime: "2013-09-27T12:15:00",
        ArrivalDateTime_str: "12:15",
        StopQuantity: 0,
        StopQuantity_str: "Direct",
        TotalDuration: "50",
        TotalDuration_str: "0h 50mins",
        SeatsRemaining_str: "2",
        NoBag_str: "",
        NonRefundable: true,
        NonRefundable_str: "Non Refundable",
        FareBasisCode: "xxx-",
        RoutingId: "",
        GroupCompStr: "ATH-SKG-1xxxxxx-UOWA3--0",
        LineCompStr: "-2013-09xxxxxxxxxxxxxxxxxxxxxA3--3,0000000-1-0--",
        TotalAmount_From_Prices: 136.64
    }

List<each_flight> Fligths_sorted = flights.OrderBy(o => o.total_price).ToList();

起始数组是列表

第一个对象是词典词典 第一个字典中的对象也是具有键/值对字符串/对象的字典 我使用object是因为类型可以是bool、int或string 现在，最后一级的词典如下所示：

List<Dictionary<string, Dictionary<string, Object>>> superduperList = new List<Dictionary<string, Dictionary<string, Object>>>();

[
{
DepartureJ: {},
ReturnJ: {},
pricesDepartureJ: {},
pricesReturnJ: {},
DepartureSegmentsJ: {},
ArrivalSegmentsJ: {}
},
...,
...,
...,
...,
...,
]

   "DepartureJ": {
        ArrivalDateTime: "2013-09-27T12:15:00",
        ArrivalDateTime_str: "12:15",
        StopQuantity: 0,
        StopQuantity_str: "Direct",
        TotalDuration: "50",
        TotalDuration_str: "0h 50mins",
        SeatsRemaining_str: "2",
        NoBag_str: "",
        NonRefundable: true,
        NonRefundable_str: "Non Refundable",
        FareBasisCode: "xxx-",
        RoutingId: "",
        GroupCompStr: "ATH-SKG-1xxxxxx-UOWA3--0",
        LineCompStr: "-2013-09xxxxxxxxxxxxxxxxxxxxxA3--3,0000000-1-0--",
        TotalAmount_From_Prices: 136.64
    }

List<each_flight> Fligths_sorted = flights.OrderBy(o => o.total_price).ToList();

现在我的问题是，我如何根据关键的TotalAmount和Prices对外部列表进行排序，它们位于列表中每个项目的每个字典的字典中

我试过与LINQ一起使用groupby，但没有工作或不知道如何使用：s

superduperList.GroupBy(each_result=> each_result["DepartureJ"]["TotalAmount_From_Prices"]);

---

如果我创建了一个新列表或更改了现有列表，这是可以的。

事实上，我是以不同的方式创建的

我创建了一个自定义类来保存数据，如下所示：

public class each_flight
{
    public Dictionary<string, object> DepartureJ = new Dictionary<string, object>();
    public Dictionary<string, object> ReturnJ = new Dictionary<string, object>();
    public Dictionary<string, object> pricesDepartureJ = new Dictionary<string, object>();
    public Dictionary<string, object> pricesReturnJ = new Dictionary<string, object>();
    public Dictionary<string, object> DepartureSegmentsJ = new Dictionary<string, object>();
    public Dictionary<string, object> ArrivalSegmentsJ = new Dictionary<string, object>();

    public double total_price;

}

然后我创造了：

List<each_flight> flights = new List<each_flight>();

然后我填充列表中的对象，然后用额外的双倍总价对它们进行如下排序：

List<Dictionary<string, Dictionary<string, Object>>> superduperList = new List<Dictionary<string, Dictionary<string, Object>>>();

[
{
DepartureJ: {},
ReturnJ: {},
pricesDepartureJ: {},
pricesReturnJ: {},
DepartureSegmentsJ: {},
ArrivalSegmentsJ: {}
},
...,
...,
...,
...,
...,
]

   "DepartureJ": {
        ArrivalDateTime: "2013-09-27T12:15:00",
        ArrivalDateTime_str: "12:15",
        StopQuantity: 0,
        StopQuantity_str: "Direct",
        TotalDuration: "50",
        TotalDuration_str: "0h 50mins",
        SeatsRemaining_str: "2",
        NoBag_str: "",
        NonRefundable: true,
        NonRefundable_str: "Non Refundable",
        FareBasisCode: "xxx-",
        RoutingId: "",
        GroupCompStr: "ATH-SKG-1xxxxxx-UOWA3--0",
        LineCompStr: "-2013-09xxxxxxxxxxxxxxxxxxxxxA3--3,0000000-1-0--",
        TotalAmount_From_Prices: 136.64
    }

List<each_flight> Fligths_sorted = flights.OrderBy(o => o.total_price).ToList();

---

所以现在可以了：

您是只想对内部字典进行排序，还是需要对外部字典进行排序？意思如果外部包含Dict1和Dict2，Dict1包含总计val 1，2，Dict2包含val 3，1。。。结果应该是什么，只是包含已排序的Dict1 1、2和Dict1、3的外部字典，还是您正在尝试对外部字典进行排序？我只想对外部列表进行排序，但这取决于内部/内部Dict的键，并且Dicts是特定的。您的字典包含对象，因此您希望将值转换为双精度。在将json解析为数据结构时，您还需要确保它存储为double。我怎样才能把它投进双倍的？双人的？还是转换成双倍？而且它总是用double填充这个值，所以它是ok的。
