MVC REST API Exclude parameter from returned Dto

I have the following (simplified) API controller:

public async Task<IHttpActionResult> GetById(int Id)
{
    var res = await _service.GetById(Id);

    return Ok(res);
}

and _service.GetById(Id) is returns returnDto.

and returnDto is as follows:

public class returnDto
{
    public int Id{get; set;}
    public string value{get;set;}
    public string extra{get;set;}
}

The issue is I want to exclude Id from returnDto when it is returned by the controller eg GetById

I know I can do this:

[DataContract]
public class returnDto
{
    public int Id{get; set;}
    [DataMember]
    public string value{get;set;}
    [DataMember]
    public string extra{get;set;}
}

but this will exclude Id from all instances of this class, whereas I only want it excluded from this method.

I also know I can make a new Dto, but this seems a bit redundant to me.

Can it be done?

You can return anonymous type:

public async Task<IHttpActionResult> GetById(int Id)
{
    var res = await _service.GetById(Id);

    return Ok(new {value = res.value, extra = res.extra});
}
