C#从网站下载的JSON文本中获取单个数据

json.net c#

Young Perry · 技术社区 · 7 年前

我已经为此搜索了很长一段时间,我没有找到任何解决我的问题的方法,这就是: 我一直在尝试从这里看到的整个源代码中分别获取json数据:

{"TargetId":0,"ProductType":null,"AssetId":1239281845,"ProductId":0,"Name":"â¤ï¸ðððððâï¸ðâ¤ï¸ Red&Black Flannel + Backpack","Description":"Shirt Image","AssetTypeId":1,"Creator":{"Id":124026176,"Name":"TheDestroyerPeter","CreatorType":"User","CreatorTargetId":124026176},"IconImageAssetId":0,"Created":"2017-12-12T19:48:24.693Z","Updated":"2017-12-12T19:48:24.693Z","PriceInRobux":null,"PriceInTickets":null,"Sales":0,"IsNew":false,"IsForSale":false,"IsPublicDomain":false,"IsLimited":false,"IsLimitedUnique":false,"Remaining":null,"MinimumMembershipLevel":0,"ContentRatingTypeId":0}

现在,我一直在尝试使用C#获取产品名称,产品名称是“红色和黑色法兰绒+背包”,我的问题是,我还没有找到提取数据的方法,当我找到数据时,我无法获得正确的数据,因为相反,如果给我“TheDestroyerPeter”

我已经编写了代码,并删除了它,它真的很草率,需要一段时间来重写,我很感激任何解决方案

您可以使用 JavaScriptSerializer 类,它是 System.Web.Script 命名空间。

例如:

var jsonString = @"{""name"":""John Doe"",""age"":20}";
var JSONObj = new JavaScriptSerializer().Deserialize<Dictionary<string, string>>(jsonString );

然后 JSONObj["name"] ; 给你 "John Doe"

在这种情况下,您可以使用它:

    public class Creator
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string CreatorType { get; set; }
        public int CreatorTargetId { get; set; }
    }

    public class RootObject
    {
        public int TargetId { get; set; }
        public object ProductType { get; set; }
        public int AssetId { get; set; }
        public int ProductId { get; set; }
        public string Name { get; set; }
        public string Description { get; set; }
        public int AssetTypeId { get; set; }
        public Creator Creator { get; set; }
        public int IconImageAssetId { get; set; }
        public DateTime Created { get; set; }
        public DateTime Updated { get; set; }
        public object PriceInRobux { get; set; }
        public object PriceInTickets { get; set; }
        public int Sales { get; set; }
        public bool IsNew { get; set; }
        public bool IsForSale { get; set; }
        public bool IsPublicDomain { get; set; }
        public bool IsLimited { get; set; }
        public bool IsLimitedUnique { get; set; }
        public object Remaining { get; set; }
        public int MinimumMembershipLevel { get; set; }
        public int ContentRatingTypeId { get; set; }
    }

使用Newtonsoft。Json

 var jsonString = @"{""TargetId"":0,""ProductType"":null,""AssetId"":1239281845,""ProductId"":0,""Name"":""â¤ï¸ðððððâï¸ðâ¤ï¸ Red&Black Flannel + Backpack"",""Description"":""Shirt Image"",""AssetTypeId"":1,""Creator"":{""Id"":124026176,""Name"":""TheDestroyerPeter"",""CreatorType"":""User"",""CreatorTargetId"":124026176},""IconImageAssetId"":0,""Created"":""2017-12-12T19:48:24.693Z"",""Updated"":""2017-12-12T19:48:24.693Z"",""PriceInRobux"":null,""PriceInTickets"":null,""Sales"":0,""IsNew"":false,""IsForSale"":false,""IsPublicDomain"":false,""IsLimited"":false,""IsLimitedUnique"":false,""Remaining"":null,""MinimumMembershipLevel"":0,""ContentRatingTypeId"":0}";
            var obj = JsonConvert.DeserializeObject<RootObject>(jsonString);

            Console.WriteLine(obj.Creator.Name);  //"TheDestroyerPeter"
