Serialize List<int> to json using JsonConvert class

Question

I am using Newtonsoft.dll and this is the scenario,

List<int> listNumbers = new List<int>() { 1, 2, 3, 4, 5};
        var result = JsonConvert.SerializeObject(listNumbers);

the result is ,

[1,2,3,4,5]

But I want the following type of result,

 [{"cardvalue":1},{"cardvalue":2},{"cardvalue":3},{"cardvalue":4},{"cardvalue":5}]

How can I do this ?

Try-

    var result = listNumbers.Select(a => new
                {
                    cardvalue = a
                });
var jsonResult = JsonConvert.SerializeObject(result);

or serialize result directly -

  var result = JsonConvert.SerializeObject(listNumbers.Select(a => new
        {
            cardvalue = a
        }));
