QueryableAttribute doesn't support query on public field

[LianwMS]

To repro:

public class Movie
{
public string Name = null;
}

public class MoviesController : ApiController
{
[Queryable]
public IEnumerable Get()
{

return new Movie[] {
  new Movie {
    Name = "Test"
  }
}

}
}

Send request: [ http://localhost/api/Movies?filter=Name eq null Response:
HTTP/1.1 ](http://localhost/api/Movies?filter=Name eq null

Response:

HTTP/1.1) 400 Bad Request

This is by design. We support only public properties.

We should support public fields in our conventional model builder by default, and customer can use IgnoreDataMember to opt out.

OData formatter does not serialize public fields today.

if we decided to support public fields, then we should change the formatter as well as model builder to understand fields.

We support only public properties. Close it.
