Deserialize JSON string to c# object

Question

My Application is in Asp.Net MVC3 coded in C#. This is what my requirement is. I want an object which is in the following format.This object should be achieved when I deseri

Answer 1

I think the JavaScriptSerializer does not create a dynamic object.

So you should define the class first:

class MyObj {
    public int arg1 {get;set;}
    public int arg2 {get;set;}
}

And deserialize that instead of object:

serializer.Deserialize<MyObj>(str);

Not testet, please try.

Answer 2

Use this code:

var result=JsonConvert.DeserializeObject<List<yourObj>>(jsonString);

Answer 3

solution :

 public Response Get(string jsonData) {
     var json = JsonConvert.DeserializeObject<modelname>(jsonData);
     var data = StoredProcedure.procedureName(json.Parameter, json.Parameter, json.Parameter, json.Parameter);
     return data;
 }

model:

 public class modelname {
     public long parameter{ get; set; }
     public int parameter{ get; set; }
     public int parameter{ get; set; }
     public string parameter{ get; set; }
 }

Answer 4

I believe you are looking for this:

string str = "{\"Arg1\":\"Arg1Value\",\"Arg2\":\"Arg2Value\"}";
JavaScriptSerializer serializer1 = new JavaScriptSerializer();
object obje = serializer1.Deserialize(str, obj1.GetType());

Answer 5

This may be useful:

var serializer = new JavaScriptSerializer();
dynamic jsonObject = serializer.Deserialize<dynamic>(json);

Where "json" is the string that contains the JSON values. Then to retrieve the values from the jsonObject you may use

myProperty = Convert.MyPropertyType(jsonObject["myProperty"]);

Changing MyPropertyType to the proper type (ToInt32, ToString, ToBoolean, etc).

Answer 6

Same problem happened to me. So if the service returns the response as a JSON string you have to deserialize the string first, then you will be able to deserialize the object type from it properly:

string json= string.Empty;
using (var streamReader = new StreamReader(response.GetResponseStream(), true))
        {
            json= new JavaScriptSerializer().Deserialize<string>(streamReader.ReadToEnd());

        }
//To deserialize to your object type...
MyType myType;
using (var memoryStream = new MemoryStream())
         {
            byte[] jsonBytes = Encoding.UTF8.GetBytes(@json);
            memoryStream.Write(jsonBytes, 0, jsonBytes.Length);
            memoryStream.Seek(0, SeekOrigin.Begin);
            using (var jsonReader = JsonReaderWriterFactory.CreateJsonReader(memoryStream, Encoding.UTF8,          XmlDictionaryReaderQuotas.Max, null))
            {
                var serializer = new DataContractJsonSerializer(typeof(MyType));
                myType = (MyType)serializer.ReadObject(jsonReader);

            }
        }

4 Sure it will work.... ;)
