Passing an associative array using json: what type to expect in the controller?

On the client side, I have an associative array where I store pairs of "Guid" - "int". I pass the array to the server using json:

  $.ajax({
      url: methodUrl,
      type: 'POST',
      async: false,
      data: { values: items },
      dataType: 'json',
      success: function (data) {
          //...
      }
  });

The object I'm trying to transfer looks like this (taken from the Chrome debugger):

  items: Object
  44f871e0-daee-4e1b-94c3-76d633a87634: 1
  698ce237-3e05-4f80-bb0d-de948c39cd96: 1

In the controller, I have a method

  public ActionResult Method(Dictionary<Guid, int> values)
  {

  }

However, the property values ​​remain zero. Having only the Guides list on the client side and List in the controller, everything works fine. I suspect that I should choose a different type for the values ​​in the controller, and not in the dictionary. I also tried adding “traditional: true” to the ajax request, however without success.

Any advice is appreciated!

items.SecondNumber = yourVariable; 
// In reality, you'd have a loop around your items and set this SecondNumber.

var data = {
    values: items

var obj = $.toJSON(data);


public CustomObject 
{
     public Guid MyGuid { get; set; }
     public int MyNumber { get; set; }
     public int SecondNumber { get; set; } // This is why we use CustomObject
