C# Web API Optional parameters in query string

Question

I have this piece of code in my controller:

[HttpGet]
[Route("team={team}&model={model}&date={date}&distance={distance}")]
public IHttpActionResult FindVehicle([FromUri]string team = "", [FromUri]string model = "", [FromUri]DateTime? date = null, [FromUri]double distance = 0.0)
    { }

All of the parameters of the query string can be optional, which is why I used the default values.

However, I am not sure what the route should be, since now, when I don't specify the model parameter for example, its value in the endpoint ends up being "model", and not "".

You don't have to define FromUri elements inside Route attribute, they will be bound out of the box:

[HttpGet]
[Route("route_name")]
public IHttpActionResult FindVehicle([FromUri]string team = "", [FromUri]string model = "", [FromUri]DateTime? date = null, [FromUri]double distance = 0.0)
{ 

}

If you are using, ASP.Net Core, then you should use [FromQuery] instead
