ASP.NET Web API model binding - different parameters names

Question

Is it possible to map parameters from request to properties with different names? I need it because I'd like to use words splitted by underscore as url parameters but in C# code I'd like to use normal convention. Example :

?property_name=1 to property PropertyName

In the request I use [FromUri] parameter like

public IHttpActionResult DoMethod([FromUri(Name = "")] SomeInput input)

Initially I thought that model binding is performed by Json serializer but probably it isn't. I tried DataMember attribute as well but these approaches do not work.

public class SomeInput
{
    [JsonProperty("property_name")]
    [DataMember(Name = "property_name")]
    public int PropertyName { get; set; }
}

I read about the custom binders but I hope some more simple way must exist. Any idea how to do this correctly and simple in ASP.NET Web API 2 with using Owin and Katana?

Did you make some changes in your web api configuration? like: formatters, converters etc — MaKCbIMKo, May 02 '16 at 15:38

You can do a remapping for an individual parameter using the Name property on [FromUri]:

public IHttpActionResult DoMethod([FromUri(Name = "property_name")] int propertyName)

To remap inside a custom object you will need to create a model binder.

It is no solution. I have multiple properties inside SomeInput. I use only simplified code in this example. – Jozef Cechovsky May 02 '16 at 16:43
You can do this for as many properties as you'd like. Obviously, it's tedious with a lot of fields. – Dan Harms May 02 '16 at 16:53
Yes yo're right but I have more things in wrapping object SomeInput like validations, comments to generate documentation etc. – Jozef Cechovsky May 03 '16 at 07:24
You can always build that object with these fields. – Dan Harms May 03 '16 at 13:32
