c# - Posting multilevel nested json data to ASP.NET MVC

I'm trying to have an array of pairs of string (key/value), here (name/acronym), and trying to loop in these 5 pairs.

My jquery ajax is this one:

    var vJson = {
                "Guid": "ccda117f-a9b5-4f54-ab4a-07a9cf403ef7",
                "Donnees":
                    {
                        "Shops":
                            [
                                { "Name": "Shop1", "Acronym": "ACRO1" },
                                { "Name": "Shop2", "Acronym": "ACRO2" },
                                { "Name": "Shop3", "Acronym": "ACRO3" },
                                { "Name": "Shop4", "Acronym": "ACRO4" }
                            ]
                        }
};

            $.ajax({
            url:"https://www.mywebsite.net/api/Create",
            data: vJson,
            type:"POST",
            dataType: 'json',
            success: function(data) {
                    console.log(data);
                }
            }
        );

My c# controller is

  public class ShopController : Controller
  {     
      [HttpPost]
      public string Create(message postMessage)
      {
          string guid = postMessage.Guid;
          (...)
      }
  }

The objects are

public class message
{
    public string Guid { get; set; }
    public shop Shops { get; set; }
}

public class shop
{
    public string Name { get; set;}
    public string Acronym { get; set;}
}

In the controller, when I ask for the guid, it works perfectly (in the code). However, I don't know how to create an array of elements [Shop1/ACRO1, Shop2/ACRO2...] and how to loop through this array? I tried postMessage.Donnees.Shops[0].Name.ToString but without any success. I think I miss an object Shops in my code but how to insert it in the other object?

I think at a point, I have to create a Dictionary object but where and how do I do that?

So my main problem is that nested array of objects in json. PLEASE, someone can put me on the tracks? It would be really appreciated!

Your json should be like

 var vJson = {
                "Guid": "ccda117f-a9b5-4f54-ab4a-07a9cf403ef7",
                "Shops": [
                                { "Name": "Shop1", "Acronym": "ACRO1" },
                                { "Name": "Shop2", "Acronym": "ACRO2" },
                                { "Name": "Shop3", "Acronym": "ACRO3" },
                                { "Name": "Shop4", "Acronym": "ACRO4" }
                            ] 
              };

and your message class should be

    public class message
    {
       public string Guid { get; set; }
       public Ilist<shop> Shops { get; set; }
    }

then you can loop like 

     foreach(var shop in postmessage.Shops)
       {
       //some code
       }

Note:-your naming convention is not ok class name should be in Passcal case like message should be Message and in javascript you should use camel case like Guid should be guid.
