Question

In the following class

using System;

namespace Beverati.Repository.ViewModel
{

[Serializable]
public class CollectionItem : EditableEntityBase
{

public CollectionItem() {}

private int? _quantity;
private string _retailValue;
private string _currencyName;

public int? quantity
{
  get { return this._quantity ?? NULL_INTEGER; }
  set { this._quantity = value; }
}

public string retailValue
{
  get { return this._retailValue ?? String.Empty; }
  set { this._retailValue = value; }
}

public string currencyName
{
  get { return this._currencyName ?? String.Empty; }
  set { this._currencyName = value; }
}

}
}

returned in this controller action

public IEnumerable<Repository.ViewModel.CollectionItem> GetAll()

produces this JSON output with MVC2 the JSON output like this

{
  quantity:2
  retailValue: 50.00
  currencyName: USD
}

However, when I installed MVC4 the JSON returned looks like this

{
  _quantity:2
  _retailValue: 50.00
  _currencyName: USD
}

All the property names have an underscore prefix. Why is the underscore being used and what should be done to have the public property names returned in the JSON?

The [Serializable] attribute is what’s doing it – Assuming you don’t need it for another purpose – remove the attribute and all should be well.
