【问题描述】：

我有一个 Json 字符串：

    "B" : 
    
        "JackID" : "1",
        "Faction" : "B",
        "Regard" : "24",
        "Currency" : "1340",
        "factionName" : "Buccaneer",
        "factionKing" : "22",
        "Tcurrency" : "0",
        "currencyname" : "Pieces of Eight",
        "textcolor" : "#FFFFFF",
        "bgcolor" : "#000000"
    ,
    "P" : 
    
        "JackID" : "1",
        "Faction" : "P",
        "Regard" : "20",
        "Currency" : "250",
        "factionName" : "Privateer",
        "factionKing" : "4",
        "Tcurrency" : "0",
        "currencyname" : "Privateer Notes",
        "textcolor" : "#000000",
        "bgcolor" : "#FFFF00"
    ,
    "N" : 
    
        "JackID" : "1",
        "Faction" : "N",
        "Regard" : "12",
        "Currency" : "0",
        "factionName" : "Navy",
        "factionKing" : "7",
        "Tcurrency" : "0",
        "currencyname" : "Navy Chits",
        "textcolor" : "#FFFFFF",
        "bgcolor" : "#77AADD"
    ,
    "H" : 
    
        "JackID" : "1",
        "Faction" : "H",
        "Regard" : "-20",
        "Currency" : "0",
        "factionName" : "Hiver",
        "factionKing" : "99",
        "Tcurrency" : "0",
        "currencyname" : "",
        "textcolor" : "#000000",
        "bgcolor" : "#CC9900"
    

我正在使用 James Newton-King 的 Json.NET 解析器并调用：

JackFactionList jackFactionList = JsonConvert.DeserializeObject<JackFactionList>(sJson);

我的类定义如下：

namespace Controller

    public class JackFactionList
    
        public JackFaction B;
        public JackFaction P;
        public JackFaction N;
        public JackFaction H;
    

    public class JackFaction
    
        public int JackId  get; set; 
        public string Faction  get; set; 
        public int Regard get; set;
        public int Currency get; set;
        // Faction details
        public string factionName get; set;
        public string factionKing get; set;
        public int Tcurrency get; set;
        public string currencyname get; set;
        public string textcolor get; set;
        public string bgcolor get; set;
    

这一切都有效，但原始列表可能有不同的 JackFactions，而不是 B、P、N 和 H。理想情况下，我想得到的是：

public class JackFactionList

    public List<JackFaction> factionList;

在不更改 Json 字符串的情况下，如何将 JackFactions 作为列表而不是单个对象获取？

【参考方案1】：

您可以将其序列化为字典：

var jackFactionList = JsonConvert.DeserializeObject<Dictionary<string,JackFaction>>(sJson);

然后你可以得到值：

List<JackFaction> result = jackFactionList.Values.ToList();

我知道有人会知道答案。这完美地工作。谢谢！
