Question

我正在尝试将以下json转换为域对象。

JSON：

[{"name":"McDonalds","deals":[{"desc":"Onion Rings free with Double Cheese burgers"}],"geometry":{"lat":13.073412,"lng":80.221393}},{"name":"JusSportz","deals":[{"desc":"20% off on Wilson Rackets"}],"geometry":{"lat":13.073231,"lng":80.221181}}]

型号：

    [DataContract]
    public class Deal
    {
        [DataMember(Name="name")]
        public string Store { get; set; }

        [DataMember(Name="deals")]
        public Offer[] Offers {get; set;}

        [DataMember(Name="geometry")]
        public GeoCoordinate Location { get; set; }

    }

    [DataContract]
    public class Offer
    {
        [DataMember]
        public string deal;
    }

我尝试了System.Runtime.Serialization.Json命名空间中的 DataContractJsonSerializer ，显然没有办法将字符串转换为对象。有没有其他图书馆允许我完成这项工作？或者有没有办法使用这个库完成此操作（通过将Json字符串转换为某种中间格式。）？

Answer 1

以下是我如何将JSON反序列化回我的域对象。

using (var reader = new MemoryStream(Encoding.Unicode.GetBytes("YourStringValue")))
{
     var ser = new DataContractJsonSerializer(typeof(Deal));
     return (Deal)ser.ReadObject(reader);
}

这是你在找什么？

Answer 2

尝试更改一下模型：

[DataContract]
public class Deal
{
    [DataMember(Name="name")]
    public string Store { get; set; }

    [DataMember(Name="deals")]
    public Offer[] Offers {get; set;}

    [DataMember(Name="geometry")]
    public GeoCoordinate Location { get; set; }

}

[DataContract]
public class Offer
{
    [DataMember(Name="desc")]
    public string deal { get; set; }
}

如何将json字符串反序列化为域对象？
