Before some time I have written a blog post – Converting a C# object into JSON string in that post one of reader, Thomas Levesque commented that mostly people are using JSON.NET a popular high performance JSON for creating for .NET Created by James Newton- King. I agree with him if we are using .NET Framework 4.0 or higher version for earlier version still JavaScriptSerializer is good. So in this post we are going to learn How we can convert C# object into JSON string with JSON.NET framework.

What is JSON.NET:
JSON.NET is a very high performance framework compared to other serializer for converting C# object into JSON string. It is created by James Newton-Kind. You can find more information about this framework from following link.

How to convert C# object into JSON string with JSON.NET framework:
For this I am going to use old application that I have used in previous post. Following is a employee class with two properties first name and last name.

public class Employee
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

I have created same object of “Employee” class as I have created in previous post like below.

Employee employee=new Employee
{FirstName = "Jalpesh",
LastName = "Vadgama"};

Now it’s time to add JSON.NET Nuget package. You install Nuget package via following command.

Nuget Pacake command for JSON.NET

I have installed like below.

Now we are done with adding NuGet package. Following is code I have written to convert C# object into JSON string.

string jsonString = Newtonsoft.Json.JsonConvert.SerializeObject(employee);
Console.WriteLine(jsonString);

Let's run application and following is a output as expected.
