HttpWebResponse is always null

Question

I have method which makes HTTP POST

I call this method with try catch like this

try
{
   returnString = MakePost(gatewayEnpoint, data);
   return returnString;
}
catch (System.Net.WebException ex)
{
   var response = (HttpWebResponse)ex.Response;
   if (response.StatusCode != HttpStatusCode.RequestTimeout || response.StatusCode != HttpStatusCode.InternalServerError)
   {
       return ex.Message.ToString();
   }
}

but response is always null.

How i can handle HTTP exceptions? i need status codes

thanks

Answer 1

There won't be a response if the client hasn't even managed to contact the server.

The cases in which there will be a response are for things like 404 status codes.

If you're never getting a response, then you're probably making some other mistake (e.g. trying to contact a server which doesn't exist).

I would strongly recommend that you don't return success and error cases in the same way as you're doing now, by the way.
