Proper way to use AJAX Post in jquery to pass model from strongly typed MVC3 view

I found 3 ways to implement this:

C# class:

public class AddressInfo {
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string ZipCode { get; set; }
    public string Country { get; set; }
}

Action:

[HttpPost]
public ActionResult Check(AddressInfo addressInfo)
{
    return Json(new { success = true });
}

JavaScript you can do it three ways:

1) Query String:

$.ajax({
    url: '/en/Home/Check',
    data: $('#form').serialize(),
    type: 'POST',
});

Data here is a string.

"Address1=blah&Address2=blah&City=blah&State=blah&ZipCode=blah&Country=blah"

2) Object Array:

$.ajax({
    url: '/en/Home/Check',
    data: $('#form').serializeArray(),
    type: 'POST',
});

Data here is an array of key/value pairs :

=[{name: 'Address1', value: 'blah'}, {name: 'Address2', value: 'blah'}, {name: 'City', value: 'blah'}, {name: 'State', value: 'blah'}, {name: 'ZipCode', value: 'blah'}, {name: 'Country', value: 'blah'}]

3) JSON:

$.ajax({
      url: '/en/Home/Check',
      data: JSON.stringify({ addressInfo:{//missing brackets
          Address1: $('#address1').val(),
          Address2: $('#address2').val(),
          City: $('#City').val(),
          State: $('#State').val(),
          ZipCode: $('#ZipCode').val()}}),
      type: 'POST',
      contentType: 'application/json; charset=utf-8'
});

Data here is a serialized JSON string. Note that the name has to match the parameter name in the server!!

='{"addressInfo":{"Address1":"blah","Address2":"blah","City":"blah","State":"blah", "ZipCode", "blah", "Country", "blah"}}'

You can skip the var declaration and the stringify. Otherwise, that will work just fine.

$.ajax({
    url: '/home/check',
    type: 'POST',
    data: {
        Address1: "423 Judy Road",
        Address2: "1001",
        City: "New York",
        State: "NY",
        ZipCode: "10301",
        Country: "USA"
    },
    contentType: 'application/json; charset=utf-8',
    success: function (data) {
        alert(data.success);
    },
    error: function () {
        alert("error");
    }
});

This is the way it worked for me:

$.post("/Controller/Action", $("#form").serialize(), function(json) {       
        // handle response
}, "json");

[HttpPost]
public ActionResult TV(MyModel id)
{
    return Json(new { success = true });
}
