从Ajax数据获取null

Question

I don't understand why in my controller's action I get null as string:

Here is ajax call:

var dict = { "A": "fake1", "B": "fake2" };
var data = { "dictionary": JSON.stringify(dict) };

$.ajax({
    url: '/MyController/MyMethod',
    data: JSON.stringify(data),
    type: 'POST',
    contentType: 'application/json',
    dataType: 'json'
});

And action method:

[HttpPost]
public ActionResult MyMethod( string dictionary )
{
    Dictionary<string, string> usersToNotify = new JavaScriptSerializer().Deserialize<Dictionary<string, string>>( dictionary );
    //...
}

Have you tried this?

   var dict = { "A": "fake1", "B": "fake2" };
   var data = { "dictionary": JSON.stringify(dict) };

   $.ajax({
   url: '/MyController/MyMethod',
       data: {
        dictionary:data.dictionary
       },
       type: 'POST',
       contentType: 'application/json',
       dataType: 'json'
   });
