How to convert json to readable array in ASP.Net

Question

I have JSON string that come from a WebService. I have use this code to convert it to object.

System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
object cw_values = serializer.DeserializeObject(cw_stringData);

Where cw_stringData is my JSON.

It returns an object{object[69]} to me. for example it means that it contains 69 items as its first level.

I have convert it again by this code.

object[] final_cw_values = ((object[])(cw_values));

So now final_cw_values has type object[] .

Each 69 items in final_cw_values have this type.

object {System.Collections.Generic.Dictionary<string,object>}

That have 15 items in it.

Each inner item have type:

System.Collections.Generic.KeyValuePair<string,object>

That contain one Key and one Value.

I need to have these Value in an Array.

If I click at Value and click Add to Watch I have some code like this but it don't work in my code.

(new System.Collections.Generic.Mscorlib_DictionaryDebugView<string,object>(((System.Collections.Generic.Dictionary<string,object>)(final_cw_values[0])))).Items[0].Value

This is part of my JSON:

Better if you create strongly typed class.

public class Data
{
    public int FirstWeight { get; set; }
    public int SecondWeight { get; set; }
    public string attr { get; set; }
    public string FirstLevel { get; set; }
    public string Hidden1 { get; set; }
    public string SecondLevel { get; set; }
    public string Hidden2 { get; set; }
    public string ThirdLevel { get; set; }
    public string Hidden3 { get; set; }
    public string ProfileCode { get; set; }
    public int ThirdWeight { get; set; }
    public int FirstEffectiveWeight { get; set; }
    public int SecondEffectiveWeight { get; set; }
    public double ThirdEffectiveWeight { get; set; }
    public int Clustering { get; set; }
}

And convert like

JavaScriptSerializer serializer = new JavaScriptSerializer();
List<Data> lstValues = serializer.Deserialize<List<Data>>(cw_stringData);

it is possible using NewtonSoftJson library nuget.org/packages/newtonsoft.json I reckon, you can also use serializer.Deserialize which will return dynamic object if you are ok with it. Nonetheless, Rashmin answer is best approach

Rashmin Javiya Over a year ago

NewtonJson is external library, if .Net framework provides facility why do we use 3rd party library. :)

aamir sajjad Over a year ago

I agree. However, NewtonSoftJson has few additional methods which can be helpful. Nonetheless, in this problem context you are right. it was just suggestion from my side.

Rashmin Javiya Over a year ago

Yes you are right too! in certain cases NewtonJson is good and has much more features. but here JavaScriptSerializer could handle easily.
