ASP MVC - create json structure

Question

i have a problem. I would like create this json structure in ASP Controller:

{
"title": "T1",
"data": [
    { "value": "v1", "key": "k1" },
    { "value": "v2",       "key": "k2" }
]
}

I tried this:

var data = new
        {
            title = "T1",
            data = new[]
            {
                new
                {
                    value = "V1",
                    key= "K1"
                },
                new
                {
                    value = "V2",
                    key= "K2"
                }
            }
        };

Thanks for advice

You can use Json method in your controller's action:

    [HttpGet]
    public ActionResult GetJsonData()
    {
        var data = new
        {
            title = "T1",
            data = new[]
            {
                new
                {
                    value = "V1",
                    key = "K1"
                },
                new
                {
                    value = "V2",
                    key = "K2"
                }
            }
        };
        return Json(data, JsonRequestBehavior.AllowGet);
    }

@bluray I get the structure that you need with code which I provided (here the output of my browser prnt.sc/auwzxd). What version of ASP.NET MVC do you use?

You can use either JsonConvert.SerializeObject() method from Newtonsoft.Json package to convert your data object to string in json format:

var json = JsonConvert.SerializeObject(data);

You can use the excellent Json.Net like:

JObject jsonObject = JObject.FromObject(data);
var json = jsonObject.ToString();

Where data is your anonymous object you posted above.
Json.Net can be downloaded via Nuget as Install-Package Newtonsoft.Json

(If it's a controller action you can just return Json(data))
