json - Obfuscation for Asp MVC using SmartAssembly or CryptoObfuscator -

i have question in using cryptoobfuscator or redgate smartassembly obfuscate asp mvc assemblies :

it seems when use 1 of these tools obfuscate assemblies, rename properties of classes, right?

so think because of operation lose access of values in json format comes server during serialization ( mean because of renaming properties cant parse json object in js correctly)

if true, how can prevent loosing parsejson operation in js?

let me include more details :

consider class structure

public class myclass {    public string fname{get;set;}    . . . }  //samplecontroller :  public jsonresult getjson() {   return json(new myclass{fname = "alex"}); } 

now in clientside :

$.ajax({   url: "/sample/getjson",   context: document.body }).success(function(data) {   //this problem : can access fname or not? var fname = jquery.parsejson(data).fname; }); 

basically obfuscators do not change return value's property's names.
if obfuscator so... can accomplish using following in ajax call:

$.ajax({   url: "/sample/getjson",   datatype: "json"   success: function(data) {         var transformeddata = {fname:arguments[0], somethingelse:arguments[1]};     //or     var fname = arguments[0];     //do rest here...   } }); 

you can use [donotobfuscate] attribute in "smart assembly" using this, can prevent json results being obfuscated @ (on server side).
there should (other/same) strategies other obfuscators.
use cryptoobfuscator , has options prevent (what/where) ever you'd being obfuscated.
