Question

I have a JSON in a web server like this :

{"My Book List": [{"ID":"5","TYPE":"History","TITLE":"Ekannoborti","PRICE":"200","IMAGE":"Ekannoborti.jpg","DOWNLOAD LINK":"http://www.starhostbd.com/"}],"success":3} 

To deserialize it I have done so far :

 public class Attributes
    {
        public string ID{ get; set; }
        public string TYPE { get; set; }
        public string TITLE { get; set; }
        public string  PRICE { get; set; }
        public string IMAGE { get; set; }
        public string DOWNLOADLINK { get; set; }
    }

    public class DataJsonAttributeContainer
    {
        public List<Attributes> attributes { get; set; }
        //public Attributes attributes { get; set; }
    }

    public static T DeserializeFromJson<T>(string json)
    {
        T deserializedProduct = JsonConvert.DeserializeObject<T>(json);
        return deserializedProduct;
    }

& in my code :

void webClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
    {
        //var deserializedJSON = JsonConvert.DeserializeObject<Attributes>(e.Result);
        var container = DeserializeFromJson<DataJsonAttributeContainer>(e.Result);
        string asd = container.attributes[0].DOWNLOADLINK[0].ToString();
        //string asd = deserializedJSON.DOWNLOADLINK[0].ToString();
    } 

The problem is : From debug wiindow i can see that data is assigned in e.Result but container remains null . How to solve this problem ? Please help !

Answer 1

Add a JsonProperty attribute to the attributes property to match the property name in the JSON, like so:

public class DataJsonAttributeContainer
{
    [JsonProperty("My Book List")]
    public List<Attributes> attributes { get; set; }
}

Also, you should add a JsonProperty attribute to the Attributes.DOWNLOADLINK property with “DOWNLOAD LINK” value in order for it to match the JSON property name.
