Question

I am developing facebook app in which i am fetching user’s friend detail in as

dynamic result = client.Get("me/friends"); //it gives friend's data for id, name

it gives data in

{
  "data": [
    {
      "name": "Steven", 
      "id": "57564897"
    }, 
    {
      "name": "Andy", 
      "id": "8487581"
    }
}

Now i would like to parse this data and store it. so that i can use it my way.

I was trying to parse it using JSON.NET and show the data in view as

var model = JsonConvert.DeserializeObject<FriendDetail>(result.data);

in the class :

public class FriendDetail
    {
        public string id { get; set; }
        public string name { get; set; }

        public FriendDetail(string i, string n)
        {
            id = i;
            name = n;
        }
    }

Now so that i can pass the view as “return View(model)“

But its giving me error: The best overloaded method match for 'Newtonsoft.Json.JsonConvert.DeserializeObject<FBApp.Models.FBFriendDetail>(string)' has some invalid arguments

Why this error is occurring ?

Please help me to parse this json data.

Also is there any better way to parse and Store json data and also then show in view ?

Please help

Answer 1

You are trying to deserialize a list of FriendDetail objects into a single FriendDetail object. Try the following:

var jObject = JObject.Parse(result.ToString());
var model = JsonConvert.DeserializeObject<List<FriendDetail>>(jObject["data"].ToString());

EDIT

This is how I tested it:

var result = 
    @"{
        ""data"": [
        {
            ""name"": ""Steven"", 
            ""id"": ""57564897""
        }, 
        {
            ""name"": ""Andy"", 
            ""id"": ""8487581""
        }]
    }";

var jObject = JObject.Parse(result.ToString());
var model = JsonConvert.DeserializeObject<List<FriendDetail>>(jObject["data"].ToString());
