Convert Json to C# Object

In this article we will cover how to Convert or Deserialize Json string to class object in c# using Newtonsoft library.

Newtonsoft.json is a JSON framework for .NET. Using it we can Serialize and deserialize any .NET object.

Country.cs

public class Country
{
    public int Country_Id { get; set; }
    public string Country_Title { get; set; }
    public string Country_Code { get; set; }
    public bool Country_Active { get; set; }
}

Sample Country Json

Create countries.json and add below sample data.

[
  {
    "Country_Id": 1,
    "Country_Title": "Afghanistan",
    "Country_Code": "AF",
    "Country_Active": true
  },
  {
    "Country_Id": 2,
    "Country_Title": "Aland Islands",
    "Country_Code": "AX",
    "Country_Active": true
  },
  {
    "Country_Id": 3,
    "Country_Title": "Albania",
    "Country_Code": "AL",
    "Country_Active": true
  },
  {
    "Country_Id": 4,
    "Country_Title": "Algeria",
    "Country_Code": "DZ",
    "Country_Active": true

]

Convert Json To C# Object

List<Country> countries = new List<Country>();
using (StreamReader sr = new StreamReader(Server.MapPath("~/countries.json")))
{
    countries = Newtonsoft.Json.JsonConvert.DeserializeObject<List<Country>>(sr.ReadToEnd());
}
