Convert List<string> to JSON using C# and Newtonsoft

Question

I have a List that I would like to convert to JSON using C# and Newtonsoft.

tags

[0]: "foo"
[1]: "bar"

Output to be:-

{"tags": ["foo", "bar"]}

Can anybody point me in the right direction please? I can convert the List to JSON okay but they key thing here is I need the "tags" part in the JSON which I do not get with a convert using JsonConvert.SerializeObject(tags).

The below code wraps the list in an anonymous type, and thus generates what you are looking for.

using System;
using System.Collections.Generic;
using Newtonsoft.Json;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            var list = new List<string> {"foo", "bar"};

            var tags = new {tags = list};

            Console.WriteLine(JsonConvert.SerializeObject(tags));

            Console.ReadLine();
        }
    }
}
