From HttpResponseMessage to IHttpActionResult
Coming from the first version of WebAPI, we are all familiar with ApiController actions that returns a HttpResponseMessage:
public HttpResponseMessage Get(int id)
{
var doc = _documentations[id];
if (doc==null)
{
return Request.CreateErrorResponse(HttpStatusCode.NotFound, "Documentation Not Found");
}
return Request.CreateResponse(doc);
}Now, WebAPI provides us a better way to do the same job. Here is how the code above will be using IHttpActionResult:
public IHttpActionResult Get(int id)
{
var doc = _documentations[id];
if (doc==null)
{
return NotFound();
}
return Ok(doc);
}Easier to write, easier to read!
