Convert JSON string to Dictionary in c#

Question

I have a json string like

{
    "action":"postRecord", 
     "data":{
            "0":{
                  "lid":999,
                   "cid":1234
                 },
            "1":{
                  "lid":111,
                  "cid":"6789"
                 }
        }
}

and

i want it co convert to Dictionary object so that i can get the data and iterate over it like data[0][lid] = 999 data[0][cid] =1234 data[1][lid] = 111 data[1][cid] = 6789

The problem is that i have to use ONLY Native Libraries of .net and I have version 2.0

you will have to go for data[0]["cid"] / data[0]["lid"] as in other cases you will get undefined Error for cid/lid — Vogel612

Is there a reason you can't use outside libraries? Json.Net is the correct answer and there's a 2.0 version: james.newtonking.com/pages/json-net.aspx — Chris Moschini

The environment in which i want it to work does not allow Outside DLL may be because of Security Issues — Dinkar Thakur

You can do

Dictionary<string, object> obj = JsonConvert.DeserializeObject<Dictionary<string, object>>(Convert.ToString(data));

using JSON.NET

If you can use .NET 3.5 (I was not sure whether your restriction to .NET 2.0 may be extended to 3.5) then this other question on the same topic has this great answer:

string json = @"{ ""id"": 13, ""value"": 255 }";

var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();

var dict = serializer.Deserialize<Dictionary<string, int>>(json);

You need to add a reference to System.Web.Extensions to use that class.

Thanks for the reply but I was stuck on 2.0 :( . I made a custom class to handle the situation though it take time.
