Question

I am trying to convert the following json into a domain object .

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}}]

Model:

    [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;
    }

I tried the DataContractJsonSerializer that is in the System.Runtime.Serialization.Json namespace and there is apparently no way to convert a string into an object. Are there any other libraries which allow me to get this done? Or is there a way to get this done using this library (by converting the Json string to some intermediate format.)?

Answer 1

Here’s how I deserialize JSON back to my domain objects.

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

Is this what you were looking for?
