OData JSON camelCase

Question

I want to use the CamelCasePropertyNamesContractResolver for the OData JSON response. How can I achieve this. With the follwoing Code Fragment only the webapi calls are considered.

regards

WebApiConfig.cs

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // New code:
        ODataModelBuilder builder = new ODataConventionModelBuilder();
        builder.EntitySet<Configuration>("Configurations");
        config.MapODataServiceRoute(
            routeName: "ODataRoute",
            routePrefix: "odata",
            model: builder.GetEdmModel());

        config.Routes.MapHttpRoute(
            name: "API Default",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

        config.Formatters.JsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
        config.Formatters.Remove(config.Formatters.XmlFormatter);
    }
}

Global.asax.cs

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();


        var config = GlobalConfiguration.Configuration;
        var settings = new JsonSerializerSettings { ContractResolver = new CamelCasePropertyNamesContractResolver() };
        config.Formatters.JsonFormatter.SerializerSettings = settings;

        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        GlobalConfiguration.Configure(WebApiConfig.Register);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
    }
}

Only want to serialize the payload in the response as camel case and the one in request is still pascal case? — Tan Jinfu, Jul 24 '14 at 23:58
Should be work in both directions (request model match should also be work) — Marko, Jul 25 '14 at 08:24

You can use the EnableLowerCamelCase extension method:

using System.Web.OData.Builder;
using System.Web.OData.Extensions;

var builder = new ODataConventionModelBuilder();
builder.EnableLowerCamelCase();

what about OData V3 ? – DATEx2 Dec 04 '14 at 14:08
@DotNetWise: I think - without having checked, admittedly - that Marko's original question actually shows how to obtain this with OData V3. – Torben Koch Pløen Feb 01 '15 at 15:48
The above EnableLowerCamelCase works only for properties. It does not work for entity types and entity sets. Any suggestions for that ? – Venki Mar 16 '22 at 16:39
@Venki - you are probably better off asking that as a new question within which you clarify your actual needs :) – Torben Koch Pløen Mar 16 '22 at 20:06
