How to convert JSON response object (having dynamic objects) into C# classes or usable result object

Question

Hi, i am using an API for car HP and PCP details. When API returns the response object it has some dynamic object and objects names depending upon the parameters given during JSON call input parameters. Please tell me how can i convert / deserialize this response object into C# object. I tried JSON convert to C# classes but didn't get required results. Given below in API response object. I need to parse this result object into C# object so i can use it for displaying required values on front end.

Answer 1

you probably want to use Dictionary<> for the parameter levels. but there is not enough sample data for us to know the rules.

Answer 2

Hi,
You can check this.

Check the class: System.Web.Helpers

dynamic data = Json.Decode(json);
So serialize a json to a dynamic object

or check the newtonsoft Json tool
https://www.newtonsoft.com/json/help/html/QueryJsonDynamic.htm

Answer 3

Hi @Waqas Nadeem ,
If you're using .NET 3.5 or later, I suggest you could use DeserializeObject.

using System.Runtime.Serialization;  
using System.Runtime.Serialization.Json;  
  
 public static string Serialize<T>(T obj)  
    {  
        DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());  
        MemoryStream ms = new MemoryStream();  
        serializer.WriteObject(ms, obj);  
        string retVal = Encoding.UTF8.GetString(ms.ToArray());  
        return retVal;  
    }  
      
    public static T Deserialize<T>(string json)  
    {  
        T obj = Activator.CreateInstance<T>();  
        MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json));  
        DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());  
        obj = (T)serializer.ReadObject(ms);  
        ms.Close();  
        return obj;  
    }
