使用 JSON.Net 在 C# 中解析（非常混乱！）

Question

我想解析以下 JSON：

{"0":{"igloo_id":"0","name":"Igloo Removal","cost":"0"},"1":{"igloo_id":"1","name":"Basic Igloo","cost":"1500"},"2":{"igloo_id":"2","name":"Candy Igloo","cost":"1500"},"3":{"igloo_id":"3","name":"Deluxe Blue Igloo","cost":"4000"},"4":{"igloo_id":"4","name":"Big Candy Igloo","cost":"4000"},"5":{"igloo_id":"5","name":"Secret Stone Igloo","cost":"2000"},"6":{"igloo_id":"6","name":"Snow Igloo","cost":"1000"},"8":{"igloo_id":"8","name":"Secret Deluxe Stone Igloo","cost":"5000"},"9":{"igloo_id":"9","name":"Deluxe Snow Igloo","cost":"3000"},"10":{"igloo_id":"10","name":"Bamboo Hut","cost":"3200"},"11":{"igloo_id":"11","name":"Log Cabin","cost":"4100"},"12":{"igloo_id":"12","name":"Gym","cost":"4800"},"13":{"igloo_id":"13","name":"Split Level Igloo","cost":"4600"},"14":{"igloo_id":"14","name":"Candy Split Level Igloo","cost":"4600"},"15":{"igloo_id":"15","name":"Snowglobe","cost":"3700"},"16":{"igloo_id":"16","name":"Ice Castle","cost":"2400"},"17":{"igloo_id":"17","name":"Split Level Snow Igl","cost":"4600"},"18":{"igloo_id":"18","name":"Fish Bowl","cost":"2400"},"19":{"igloo_id":"19","name":"Tent","cost":"2700"},"20":{"igloo_id":"20","name":"Jack O' Lantern","cost":"2700"},"21":{"igloo_id":"21","name":"Backyard Igloo","cost":"4200"},"22":{"igloo_id":"22","name":"Pink Ice Palace","cost":"2400"},"23":{"igloo_id":"23","name":"Ship Igloo","cost":"4300"},"24":{"igloo_id":"24","name":"Dojo Igloo","cost":"1300"},"25":{"igloo_id":"25","name":"Gingerbread House","cost":"2100"},"26":{"igloo_id":"26","name":"Restaurant Igloo","cost":"4800"},"27":{"igloo_id":"27","name":"Tree House Igloo","cost":"4500"},"28":{"igloo_id":"28","name":"Theatre Igloo","cost":"4600"},"29":{"igloo_id":"29","name":"Circus Tent","cost":"0"},"30":{"igloo_id":"30","name":"Snowy Backyard Igloo","cost":"3000"},"31":{"igloo_id":"31","name":"Cave Igloo","cost":"1500"},"32":{"igloo_id":"32","name":"Green Clover Igloo","cost":"2050"},"33":{"igloo_id":"33","name":"Grey Ice Castle","cost":"2400"},"35":{"igloo_id":"35","name":"Cozy Cottage Igloo","cost":"2500"},"36":{"igloo_id":"36","name":"Estate Igloo","cost":"2500"},"37":{"igloo_id":"37","name":"In Half Igloo","cost":"2300"},"38":{"igloo_id":"38","name":"Shadowy Keep","cost":"2400"},"39":{"igloo_id":"39","name":"Dragon's Lair","cost":"3000"},"40":{"igloo_id":"40","name":"Mermaid Cove","cost":"3030"},"41":{"igloo_id":"41","name":"Whale's Mouth","cost":"2700"},"42":{"igloo_id":"42","name":"Trick-or-Treat Igloo","cost":"2000"},"43":{"igloo_id":"43","name":"Deluxe Gingerbread House","cost":"0"},"45":{"igloo_id":"45","name":"Invisible Snowy","cost":"0"},"46":{"igloo_id":"46","name":"Invisible Beach","cost":"0"},"47":{"igloo_id":"47","name":"Invisible Forest","cost":"0"},"48":{"igloo_id":"48","name":"Invisible Mountain","cost":"0"},"49":{"igloo_id":"49","name":"Shipwreck Igloo","cost":"900"},"50":{"igloo_id":"50","name":"Wildlife Den","cost":"900"},"51":{"igloo_id":"51","name":"Medieval Manor","cost":"1200"},"52":{"igloo_id":"52","name":"Warehouse","cost":"950"},"53":{"igloo_id":"53","name":"Pineapple Igloo","cost":"0"},"54":{"igloo_id":"54","name":"Creepy Cavern","cost":"1500"},"55":{"igloo_id":"55","name":"Frost Bite Palace","cost":"0"},"56":{"igloo_id":"56","name":"Fresh Baked Gingerbread House","cost":"2500"},"57":{"igloo_id":"57","name":"Penthouse","cost":"4000"},"58":{"igloo_id":"58","name":"VIP Penthouse","cost":"0"},"59":{"igloo_id":"59","name":"Invisible Age of Dinosaurs","cost":"0"},"60":{"igloo_id":"60","name":"Puffle Tree Fort","cost":"0"},"61":{"igloo_id":"61","name":"Secret Base","cost":"1600"},"62":{"igloo_id":"62","name":"Death Star Igloo","cost":"1000"},"63":{"igloo_id":"63","name":"Beach Party Igloo","cost":"1500"},"64":{"igloo_id":"64","name":"Gymnasium Igloo","cost":"0"},"65":{"igloo_id":"65","name":"Magical Hideout","cost":"1500"},"66":{"igloo_id":"66","name":"Eerie Castle","cost":"2000"},"67":{"igloo_id":"67","name":"Sweet Swirl Igloo","cost":"0"},"68":{"igloo_id":"68","name":"Train Station Igloo","cost":"1100"},"69":{"igloo_id":"69","name":"Main Event Igloo","cost":"1000"},"70":{"igloo_id":"70","name":"CP Airliner","cost":"1200"}}

, name and cost .我需要一种方法来检索 、 name和cost 。

我已经尝试了以下，但这不是我想要的

List<Igloo> igloosList = JsonConvert.DeserializeObject<List<Igloo>>(itemJson);

这是我班级的结构

namespace Canvas
{
    public class Igloo
    {
        public int cost;
        public int igloo_id;
        public string name;

        public int Cost
        {
            get
            {
                return cost;
            }
        }

        public int Id
        {
            get
            {
                return igloo_id;
            }
        }

        public string Name
        {
            get
            {
                return name;
            }
        }
    }
}

Answer 1

使用JsonProperty属性：

[JsonProperty(PropertyName = "cost")]    
public int Cost
    {
        get
        {
            return cost;
        }
        private set { cost = value; }
    }

    [JsonProperty(PropertyName = "igloo_id")]
    public int Id
    {
        get
        {
            return igloo_id;
        }
        private set { igloo_id = value; }
    }
    [JsonProperty(PropertyName = "name")]
    public string Name
    {
        get
        {
            return name;
        }
        private set { name = value; }
    }

基本上，您需要为每个属性说明匹配的 Json 键是什么。 另外，您需要为您的每个属性设置一个 setter，但它可以是私有的。

Answer 2

我不完全确定我明白你想要什么。 您发布的代码在我尝试运行时生成了异常，

附加信息：无法将当前 JSON 对象（例如 {"name":"value"}）反序列化为类型“System.Collections.Generic.List1[ConsoleApplication2.Program+Igloo]”，因为该类型需要一个 JSON 数组（例如 [1 ,2,3]) 以正确反序列化。

如果我使用，它确实反序列化了：

var igloosList = JsonConvert.DeserializeObject<Dictionary<string, Igloo>>( json );

如果你想遍历它，你可以使用：

foreach( var igloo in igloosList.Values )
