Constructing multipart response

Question

Given the reposne of multiple HTTP request, I have to build a multipart response out of them. The problem I am faing is how to set the response headers of individual response in the final multipart response. For. eg.

HttpClient client = new HttpClient();
HttpRequestMessage request1 = new HttpRequestMessage(HttpMethod.Get, "http://www.xyx/Service.svc/resource1");
HttpResponseMessage response1 = client.SendAsync(request).Result;

HttpRequestMessage request2 = new HttpRequestMessage(HttpMethod.Get, "http://www.xyx/Service.svc/resource2");
HttpResponseMessage response2 = client.SendAsync(request).Result;

MultipartContent content = new MultipartContent("mixed", "----Boundary");
content.Add(response1.Content);
content.Add(response2.Content);

The response I am getting from it is like:

------Boundary
Content-Length: 99427
Content-Type: application/json; charset=utf-8
Last-Modified: Mon, 20 Jan 2014 06:15:50 GMT

{"DebugInfo":null}
------Boundary
Content-Length: 99427
Content-Type: application/json; charset=utf-8
Last-Modified: Mon, 20 Jan 2014 06:15:50 GMT

{"DebugInfo":null}
------Boundary--

Now I want to include the reposne header of each request as part of individual response as well in the final response, and it should look like

HTTP/1.1 200 OK

Does anyone know how to add them in MultipartContent in C#?

Answer 1

Got it. You can also add complete response to a MultipartContent as well.

MultipartContent content = new MultipartContent("mixed", "----Boundary");
content.Add(new HttpMessageContext(response1));
content.Add(new HttpMessageContext(response2));
