如何將特定的Json節點反序列化為Dictionary <string,object> ？

Question

我有一個JSON響應，如下所示：

{
"success": true,
"more": false,
"results_html": "a lot of html in here",
"listinginfo": {
    "637640274112277168": {
        "listingid": "637640274112277168",
        "price": 50,
        "fee": 7,
        "publisher_fee_app": 730,
        "publisher_fee_percent": "0.10000000149011612",
        "currencyid": "2005",
        "steam_fee": 2,
        "publisher_fee": 5,
        "converted_price": 1,
        "converted_fee": 2,
        "converted_currencyid": "2003",
        "converted_steam_fee": 1,
        "converted_publisher_fee": 1,
        "converted_price_per_unit": 1,
        "converted_fee_per_unit": 2,
        "converted_steam_fee_per_unit": 1,
        "converted_publisher_fee_per_unit": 1,
        "asset": {
            "currency": 0,
            "appid": 730,
            "contextid": "2",
            "id": "6542776191",
            "amount": "1"
        }
    },
    "194035710805671301": {
        "listingid": "194035710805671301",
        "price": 0,
        "fee": 0,
        "publisher_fee_app": 730,
        "publisher_fee_percent": "0.10000000149011612",
        "currencyid": "2001",
        "asset": {
            "currency": 0,
            "appid": 730,
            "contextid": "2",
            "id": "6825071309",
            "amount": "0"
        }

    },

  }//end listinginfo
 //more fields here..
}

我需要從“listinginfo”節點獲取信息並將它們添加到dictionary<string, NewListedItem> ，其中string將是例如：“637640274112277168”，列表將是“NewListedItem”類型，包含所有信息從那個子節點。 我的課程看起來像這樣：

class listinginfo
{
    public Dictionary<string, NewListedItem> Items;

}
class Asset
{
    public string currency { get; set; }
    public string appid { get; set; }
    public string contextid { get; set; }
    public string id { get; set; }
    public string amount { get; set; }
}
class NewListedItem
{

    public string listingid { get; set; }
    public string price { get; set; }
    public string fee { get; set; }
    public string publisher_fee_app { get; set; }
    public string publisher_fee_percent { get; set; }
    public string steam_fee { get; set; }
    public string publisher_fee { get; set; }
    public string converted_price { get; set; }
    public string converted_fee { get; set; }
    public string converted_currencyid { get; set; }
    public string converted_steam_fee { get; set; }
    public string converted_publisher_fee { get; set; }
    public string converted_fee_per_unit { get; set; }
    public string converted_steam_fee_per_unit { get; set; }
    public string converted_publisher_fee_per_unit { get; set; }
    public Asset asset { get; set; }


}

我怎樣才能實現這一目標？

Answer 1

所以我無法以干凈的方式做到這一點，但我相信這正是你要找的：

 var jsonString = @"{
            'success': true,
            'more': false,
            'results_html': 'a lot of html in here',
            'listinginfo': {
                '637640274112277168': {
                    'listingid': '637640274112277168',
                    'price': 50,
                    'fee': 7,
                    'publisher_fee_app': 730,
                    'publisher_fee_percent': '0.10000000149011612',
                    'currencyid': '2005',
                    'steam_fee': 2,
                    'publisher_fee': 5,
                    'converted_price': 1,
                    'converted_fee': 2,
                    'converted_currencyid': '2003',
                    'converted_steam_fee': 1,
                    'converted_publisher_fee': 1,
                    'converted_price_per_unit': 1,
                    'converted_fee_per_unit': 2,
                    'converted_steam_fee_per_unit': 1,
                    'converted_publisher_fee_per_unit': 1,
                    'asset': {
                                        'currency': 0,
                        'appid': 730,
                        'contextid': '2',
                        'id': '6542776191',
                        'amount': '1'
                    }
                },
                '194035710805671301': {
                    'listingid': '194035710805671301',
                    'price': 0,
                    'fee': 0,
                    'publisher_fee_app': 730,
                    'publisher_fee_percent': '0.10000000149011612',
                    'currencyid': '2001',
                    'asset': {
                            'currency': 0,
                            'appid': 730,
                            'contextid': '2',
                            'id': '6825071309',
                            'amount': '0'
                        }

                },
                }
        }";
        var json = JObject.Parse(jsonString);

        List<JToken> results = json["listinginfo"].Children().Children().ToList();
        var dictionaryResults = new ListingInfo();

        foreach (var token in results)
        {
            var info = JsonConvert.DeserializeObject<NewListedItem>(token.ToString());

            List<NewListedItem> listInfo = new List<NewListedItem>();
            listInfo.Add(info);

            dictionaryResults.Items = new Dictionary<string, List<NewListedItem>>();
            dictionaryResults.Items.Add(info.Listingid, listInfo);
        }

我還修改了你的類的屬性名稱：

 public class Asset
    {
        public string Currency { get; set; }
        public string Appid { get; set; }
        public string Contextid { get; set; }
        public string Id { get; set; }
        public string Amount { get; set; }
    }
    public class NewListedItem
    {

        public string Listingid { get; set; }
        public string Price { get; set; }
        public string Fee { get; set; }
        [JsonProperty("publisher_fee_app")]
        public string PublisherFeeApp { get; set; }
        [JsonProperty("publisher_fee_percent")]
        public string PublisherFeePercent { get; set; }
        [JsonProperty("steam_fee")]
        public string SteamFee { get; set; }
        [JsonProperty("publisher_fee")]
        public string PublisherFee { get; set; }
        [JsonProperty("converted_price")]
        public string ConvertedPrice { get; set; }
        [JsonProperty("converted_fee")]
        public string ConvertedFee { get; set; }
        [JsonProperty("converted_currencyid")]
        public string ConvertedCurrencyid { get; set; }
        [JsonProperty("converted_steam_fee")]
        public string ConvertedSteamFee { get; set; }
        [JsonProperty("converted_publisher_fee")]
        public string ConvertedPublisherFee { get; set; }
        [JsonProperty("converted_fee_per_unit")]
        public string ConvertedFeePerUnit { get; set; }
        [JsonProperty("converted_steam_fee_per_unit")]
        public string ConvertedSteamFeePerUnit { get; set; }
        [JsonProperty("converted_publisher_fee_per_unit")]
        public string ConvertedPublisherFeePerUnit { get; set; }
        public Asset Asset { get; set; }


    }

Answer 2

你真的很親密。 除了需要將根類中的字典屬性的名稱從Items更改為listinginfo以鏡像JSON屬性名稱之外，您的類將在您定義它們時正常工作。 （或者，您可以使用[JsonProperty]屬性將Items字典映射到JSON中的listinginfo屬性。）進行更改后，我還建議將您的根類從listinginfo重命名為對您有意義的其他內容，例如也許是ListingResponse ，但這不是絕對必要的。

完成這些更改后，您的根類應如下所示：

public class ListingResponse
{
    public Dictionary<string, NewListedItem> listinginfo { get; set; }
}

或者，如果您更喜歡屬性方法：

public class ListingResponse
{
    [JsonProperty("listinginfo")]
    public Dictionary<string, NewListedItem> Items { get; set; }
}

然后，您應該能夠將JSON反序列化到此類中，並且您的字典將按預期填充：

ListingResponse response = JsonConvert.DeserializeObject<ListingResponse>(json);
