I need to get response from url using the following headers:

HttpClient httpClient = new HttpClient();
httpClient.DefaultRequestHeaders.Add("Content-Type", "application/json");
httpClient.DefaultRequestHeaders.Add("X-apiKey", App.API_Key);
string responseAsString = await httpClient.GetStringAsync("http://......./");

it stop running at this line without any value for responseAsString:

 httpClient.DefaultRequestHeaders.Add("Content-Type", "application/json");

Any errors? Can you post the stack trace? – RockThunder Nov 20 '14 at 09:06

`Content-Type` is a response, not a request header. If you check the response status of your call I suspect you received a `400` error. Use the `Accept` header to specify the format you want – Panagiotis Kanavos Nov 20 '14 at 09:07
@PanagiotisKanavos, I suggest you to read [this](http://en.wikipedia.org/wiki/List_of_HTTP_header_fields) or [this](http://tools.ietf.org/html/rfc2046) – Hamlet Hakobyan Nov 20 '14 at 09:24
@RockThunder no errors – ahmad Nov 20 '14 at 09:25
@tanaydin not effective in this case – ahmad Nov 20 '14 at 09:26
@HamletHakobyan `GetStringAsync` is a `GET` request. `GET` requests have no body, hence no `Content-Type` is allowed – Panagiotis Kanavos Nov 20 '14 at 09:34
@ahmad what is the HTTP response status code? Use `SendAsync` to get the actual response object or use Fiddler to check what the server actually returns. – Panagiotis Kanavos Nov 20 '14 at 09:36
here is the problem httpClient.DefaultRequestHeaders.Add("Content-Type", "application/json"); – ahmad Nov 20 '14 at 09:44
@PanagiotisKanavos, "Content-Type is a response, not a request header." this is from your comment. – Hamlet Hakobyan Nov 20 '14 at 10:01
