Parse HTTP response in C#

Question

I want to split HttpResponse using C#.

I got a response like this:

&url=http:\\\example.com&type=abcd&quality=best

I want to store url and type in a string I don't know how to do this. I can do this in Java like this:

String response = GetURL("http://example2.com?info_id=" + id);
String Info = DecodeUrlFormEncoded(response);
String url = Info.get("url");
String type = Info.get("type");

I have done my Coding Like this

        string str = "http://www.youtube.com/get_video_info?video_id=tmeOjFno6Do";
        Stream objStream;
        StreamReader objSR;
        System.Text.Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
        HttpWebRequest wrquest = (HttpWebRequest)WebRequest.Create(str);
        HttpWebResponse getresponse = null;
        getresponse = (HttpWebResponse)wrquest.GetResponse();

        objStream = getresponse.GetResponseStream();
        objSR = new StreamReader(objStream, encode, true);
        string strResponse = objSR.ReadToEnd();

Got this response

Decoded response using this code

string videoInfo = System.Web.HttpUtility.UrlDecode(strResponse);

Now i want to split decoded response like this coded in java

String[] formats = strResponse.get("url_encoded_fmt_stream_map").split(",");

How to code this in c#

Answer 1

Try this:

var coll = System.Web.HttpUtility.ParseQueryString(queryString);
string url = coll["url"];
string type = coll["type"];
