How to throw exception in Web API?

.net, asp.net-web-api, c#, exception

Solution

It's absolutely fine.

Alternatively, if you wish to provide more info (to allow, as you say, the client to distinguish from regular 404):

    if (test == null)
    {
         throw new HttpResponseException(Request.CreateErrorResponse(HttpStatusCode.NotFound, 
"this item does not exist"));
    }

Problem

How can I throw a exception to in ASP.net Web Api? Below is my code: ``` public Test GetTestId(string id) { Test test = _test.GetTest(id); if (test == null) { throw new HttpResponseException(HttpStatusCode.NotFound); } return test; } ``` I don't think I am doing the right thing, How do my client know it is a `HTTP 404` error?
