Convert Array into JSON String in ASP.NET C#

Question

I have a simple array that looks like this:

{"image_01.jpg","image_02.jpg","image_03.jpg"}

I need to format it into this:

[{"small":"image_01.jpg","big":"image_01.jpg"},{"small":"image_02.jpg","big":"image_02.jpg"}, {"small":"image_03.jpg","big":"image_03.jpg"}]

I am very new to ASP.NET C#, I've been trying the examples here: https://msdn.microsoft.com/en-us/library/2yd9wwz4.aspx but I am not sure how to implement them into my array.

Answer 1

you need to import the System.Linq and System.Web.Script.Serialization namespaces and then use the following code:

var array = new string[] { "image_01.jpg", "image_02.jpg", "image_03.jpg" };
var newArray = array.Select(x => new { small = x, big = x }).ToArray();

var serializer = new JavaScriptSerializer();
var json = serializer.Serialize(newArray);
