I'm trying to post data to a webservice (asp.net 3.5), like below (two variants, one commented):

var array = [3, 2, 5, 1, 7];
var jsonString = JSON.stringify(array);
//var jsonString = '{ "firstName": "John", "lastName": "Smith", "age": 25, "address": { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021" }, "phoneNumber": [ { "type": "home", "number": "212 555-1234" }, { "type": "fax", "number": "646 555-4567" } ] }'

$.ajax({
    type: "POST",
    url: "WebService2.asmx/AddRoute",
    data: jsonString,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    processData: "false",
    error: function(msg) {
        alert('error' + msg.toString);
    }
});

So I need a matching webmethod to recieve it. Something like this:

[WebMethod]
public string AddRoute(/* xxx */)
{
    //handle data
}

Could someone please elaborate on how I can fetch the data, where I've typed "xxx"? I would have thought "int[] array" would do the trick, but it's not working. Any help would be greatly appreciated :)
