Changing the parameter name Web Api model binding

Question

I'm using Web API model binding to parse query parameters from a URL. For example, here is a model class:

public class QueryParameters
{
    [Required]
    public string Cap { get; set; }

    [Required]
    public string Id { get; set; }
}

This works fine when I call something like /api/values/5?cap=somecap&id=1.

Is there some way I can change the name of the property in the model class but keep the query parameter name the same - for example:

public class QueryParameters
{
    [Required]
    public string Capability { get; set; }

    [Required]
    public string Id { get; set; }
}

I thought adding [Display(Name="cap")] to the Capability property would work, but it doesn't. Is there some type of data annotation I should use?

The controller would be have a method that looked like this:

public IHttpActionResult GetValue([FromUri]QueryParameters param)    
{
    // Do Something with param.Cap and param.id
}

You can use the Name property of the FromUri binding attribute to use query string parameters with different names to the method arguments.

If you pass simple parameters rather than your QueryParameters type, you can bind the values like this:

/api/values/5?cap=somecap&id=1

public IHttpActionResult GetValue([FromUri(Name = "cap")] string capabilities, int id)    
{
}
