copied!<p>I would also recommend installing json.NET but the rest is a lot easier. Below is an extension method I am using in my current application to provide better reuse, feel free to adapt it to your needs, but it should do what you need right out of the box.</p> <pre><code>public class JsonNetResult : ActionResult { public Encoding ContentEncoding { get; set; } public string ContentType { get; set; } public object Data { get; set; } public JsonSerializerSettings SerializerSettings { get; set; } public Formatting Formatting { get; set; } public JsonNetResult() { SerializerSettings = new JsonSerializerSettings { //http://odetocode.com/blogs/scott/archive/2013/03/25/asp-net-webapi-tip-3-camelcasing-json.aspx #if DEBUG Formatting = Formatting.Indented, //Makes the outputted Json easier reading by a human, only needed in debug #endif ContractResolver = new CamelCasePropertyNamesContractResolver() //Makes the default for properties outputted by Json to use camelCaps }; } public override void ExecuteResult(ControllerContext context) { if (context == null) throw new ArgumentNullException("context"); HttpResponseBase response = context.HttpContext.Response; response.ContentType = !string.IsNullOrEmpty(ContentType) ? ContentType : "application/json"; if (ContentEncoding != null) response.ContentEncoding = ContentEncoding; if (Data != null) { JsonTextWriter writer = new JsonTextWriter(response.Output) {Formatting = Formatting}; JsonSerializer serializer = JsonSerializer.Create(SerializerSettings); serializer.Serialize(writer, Data); writer.Flush(); } } } public static class JsonNetExtenionMethods { public static ActionResult JsonNet(this Controller controller, object data) { return new JsonNetResult() {Data = data}; } public static ActionResult JsonNet(this Controller controller, object data, string contentType) { return new JsonNetResult() { Data = data, ContentType = contentType }; } public static ActionResult JsonNet(this Controller controller, object data, Formatting formatting) { return new JsonNetResult() {Data = data, Formatting = formatting}; } } </code></pre> <p>Here's an example of using it.</p> <pre><code>public JsonNetResult Layar(string countryCode, string timestamp, string userId, string developerId, string layarName, double radius, double lat, double lon, double accuracy) { LayarModel model = new LayarModel(lat, lon, radius); return this.JsonNet(model); } </code></pre> <p>The part to note that solves your problem specifically is when the <code>ContractResolver</code> on the <code>JsonSerializerSettings</code> is set to use <code>new CamelCasePropertyNamesContractResolver()</code></p> <p>This way you never have to set custom naming again.</p>
