User3112162 posted

Why is it necessary?

The following 2 methods return the same response.

        [Route("Get1")]
        [HttpGet]
        public HttpResponseMessage Get1()
        {
            var resp = new HttpResponseMessage(HttpStatusCode.NotFound)
            {
                Content = new StringContent("ABC"),
                ReasonPhrase = "phrase"
            };
            throw new HttpResponseException(resp);
        }



        [Route("Get3")]
        [HttpGet]
        public HttpResponseMessage Get3()
        {
            var resp = new HttpResponseMessage(HttpStatusCode.NotFound)
            {
                Content = new StringContent("ABC"),
                ReasonPhrase = "phrase"
            };
            return resp;
        }

Hi rover83

1: HttpResponseException

What happens if a Web API controller throws an uncaught exception? By default, most exceptions are translated into an HTTP response with status code 500, Internal Server Error. The HttpResponseException type is a special case. This exception returns any HTTP status code that you specify in the exception constructor.

So, HttpResponseException is necessary. You can refer the following tutorial for getting more information.

Exception Handling in ASP.NET Web API:

http://www.asp.net/web-api/overview/error-handling/exception-handling

2: HttpResponseMessage

A HttpResponseMessage allows us to work with the HTTP protocol and unifies our return type. In simple words an HttpResponseMessage is a way of returning a message/data from your action.
