ASP.NET MVC 4 Api Controller Invalid URI: The format of the URI could not be determined

Question

I have this method here and at the end of the method, I am looking to redirect the user. I have this code:

[HttpPost]
public HttpResponseMessage Post()
{
    // Post Data to Database

    HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.Moved);
    response.Headers.Location = new Uri("/airportboard");
    return response;
}

but when I run this code, I get this error:

Invalid URI: The format of the URI could not be determined.

What am I doing wrong?

Answer 1

Here:

new Uri("/airportboard");

There isn't enough information for the Uri class to accurately parse the path you gave it. You should pass something that at least has a protocol and domain in addition to the path, such as:

new Uri("http://example.com/airportboard");

There are several ways to construct this URL without needing to know much.
