How do I return an array of json objects with dynamic keys, for example:

[
    "dynamic prop 1": {
          "title": "abc",
          "sku": "123"
        },
    "dynamic prop 2": {
          "title": "xyz",
          "sku": "789"
        }
]

The default formatting is:

[
        {
          "title": "abc",
          "sku": "123"
        },
        {
          "title": "xyz",
          "sku": "789"
        }
]

  • I'm assuming you are using the .NET dynamic type? Commented Jul 13, 2016 at 13:58
  • No. I just wanted to emphasize that the the property could be anything. For example, the title and sku are properties I know but the "key/name/id" of the object could be any string. Commented Jul 13, 2016 at 14:25

    Understood, but you are constructing this object on the server. So you can use the dynamic type and return a JObject. Commented Jul 13, 2016 at 14:37
  • Yes, on the server. Currently I'm returning this: return data.Select(x => new { title = x.title, sku = x.sku }); Commented Jul 13, 2016 at 15:05
  • use a stringbuilder and simply build the json string which you want. Commented Jul 13, 2016 at 15:31

Using JObject solved the problem:

JObject jProducts= new JObject();

foreach (var p in products)
{
    var o = new JObject()
    {
        { "title",  p.Title},
        { "sku", p.Sku }
    };

    jProducts.Add(p.Name, o);
}

return Request.CreateResponse(HttpStatusCode.OK, jProducts);

Use return List of objects. Where object (say MyObj)having properties: title and sku. then yuo will get desired output. Your data to be returned will look like: 

List<MyObj> data=new List<MyObj>();
// add your objects.
// return this list object.

u will get you output in format you want.

That's incorrect. It's the default formatting which I am getting already.

then return dynamic object.

return new{ property1Name=MyObj1,property2Name=MyObj2}

I hope this will work for you.

Otherwise refer following link to generate c# classes from json and create required model in ur solution. https://www.google.co.in/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjEl7efl_XNAhWJs48KHYDHAUsQFggfMAA&url=http%3A%2F%2Fjson2csharp.com%2F&usg=AFQjCNEbR-mTF-PU4BYWff3opCDcJOl0ag&bvm=bv.127178174,d.c2I

That's what I'm currently doing but it does not solve the problem. The "property1Name" is a variable so I can't use the above syntax.

Tuple data type and learn about it.
