Force CamelCase on ASP.NET WebAPI Per Controller

In ASP.NET WebAPI, I know you can set the default json formatter to use camel case using [CamelCasePropertyNamesContractResolver()][1] in the global.aspx which will force ALL json serialization to camel case.

However, I need to be able to set it on a "Per Controller" instance, instead of a Global solution.

Is this possible?

This Stack Overflow [answer][1] should be helpful. It shows you how to create an ActionFilter which can be applied to any action where you wish to use CamelCasing.

Yes, it's possible...you can use `IControllerConfiguration` to define per-controller specific configuration..

[This][1] is a sample which describes this scenario. You can quickly take a look at how this interface should be used over [here][2](from the sample).

Thanks to @KiranChalla I was able to achieve this easier than I thought.

Here is the pretty simple class I created:

using System;
using System.Linq;
using System.Web.Http.Controllers;
using System.Net.Http.Formatting;
using Newtonsoft.Json.Serialization;

public class CamelCaseControllerConfigAttribute : Attribute, IControllerConfiguration
{
public void Initialize(HttpControllerSettings controllerSettings, HttpControllerDescriptor controllerDescriptor)
{
var formatter = controllerSettings.Formatters.OfType<JsonMediaTypeFormatter>().Single();
controllerSettings.Formatters.Remove(formatter);

formatter = new JsonMediaTypeFormatter
{
SerializerSettings = {ContractResolver = new CamelCasePropertyNamesContractResolver()}
};

controllerSettings.Formatters.Add(formatter);

}
}

Then just add the attribute to any Controller class you want CamelCase.

[CamelCaseControllerConfig]

I know this is pretty old, but I had a problem with the accepted answer because there were other necessary changes to the formatter that were no longer present after removing and re-adding. I did this by just modifying the existing formatter as shown in this Gist: .
