Using Page Methods - simple question

I managed to call c# methods through AJAX, but now I have a simple doubt:

On my .js I have:

function criarNota() {

    var note_id = jQuery.fn.stickyNotes.createNote();
    alert("isto: "+note_id);
    PageMethods.criarNota(note_id,function(result) { // é enviado o ID da nota criada
                alert(result);
            });
            }

I send the note_id var to server.

C#

[System.Web.Services.WebMethod]
   public static string criarNota(int note_id)
   {
       try
       {
          // receives note_id, execute sql statement and I get:

           // string text
           // int id

         

           return ...........;
       }

How can I return that text and id var and how to receive it my js function?

I know how to do that, I already do it, but what I want is to return two variables (c#) and received them with JS. I can do it with one, my problem is do it with more than one.

i.e.; I want to return [text,id] so I can receive at Js like function carregarNotas(result1,result2) {

This way I get nulls again:

function verNumNotas() {

PageMethods.verNumNotas(carregarNotas);
}

function carregarNotas(result) {

var texto = result[0];
var num = result[1];

alert("istooo:" + num + "e isto "+texto);
loadNotes(num);
}

I didnt knew it, I just discovered later. Maybe I formulated a question not clearly, my apologies.

This is basic programming knowledge, a method or function has one, and only one, return object. That object however, can be a class, struct, string, etc. that contains multiple values.
