Dies kann durch das Werfen einer HttpResponseException mit dem entsprechenden HttpStatusCode erreicht werden:

if (EmailAndOrPasswordIsWrong) 
{ 
    throw new HttpResponseException(HttpStatusCode.BadRequest); // 400 
} 

if (SomethingElseGoesWrong) 
{ 
    throw new HttpResponseException(HttpStatusCode.InternalServerError); // 500 
}
