Rename Json object fieldName

Question

i am using MVC c# i have a object with

public class Person
{
        public int TypeId { get; set; }
        public string Code { get; set; }

}

i have a code that retruns JSON object for this object like this

    return Json(personCodeStore.GetBusinessCodes());

But when I receive this on the client side i want to be able to rename the field name from

TypeId to value
Code  to text

I do not want to use DataContractSerializer like MVC3 JSON Serialization: How to control the property names? because i am using EF 5.x and every time i update the model and .tt file runs it overwrites my changes and also it uses this modified property on all my views which i don't want.

So is there a way i can rename this when i serialize it or once i get on client side using jquery?

You could simply use LINQ and return an anonymous object projecting your original result:

var businessCodes = personCodeStore.GetBusinessCodes();
return Json(businessCodes.Select(x => new 
{
    value = x.TypeId,
    text = x.Code
}));

Now you're gonna get something along the lines of:

[
    { "value": 1, text = "text 1" },
    { "value": 2, text = "text 2" },
    { "value": 3, text = "text 3" }
    ...
]
