Website responding with Error message in HttpWebRequest

Question

I have two problems: First, when I am trying to get data from this website it goes well within browser but when I send request using httpwebrequest in C# it responds with this message. In first attempt it may return data but if the send request again it returns this message. Second, when I go to page-2 or click next to go to another page it generates numbers (in end) which is not consistent changes everytime I refresh browser. How can I get these numbers? For example: "=1559040099084" like this. { "message": "refresh" } HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(URI); request.Headers.Add( "IfModifiedSince" , DateTime.Now.ToString()); request.Method = "GET" ; string result = string .Empty; using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { Stream dataStream = response.GetResponseStream(); StreamReader reader = new StreamReader(dataStream); result = reader.ReadToEnd(); reader.Close(); dataStream.Close(); } Debug.Write(result); https://www.rajalacamera.fi/tuotteet/objektiivit https://www.rajalacamera.fi/alt_api/category/?category_id=29&p=2&product_list_order=position&product_list_dir=asc&_=1559040099084

Hi Subbarao, I am sorry but still .End does not work. I am getting Error message "streamreader/HttpWebResponse does not contain a definition for 'End"

Hi try this using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { Stream dataStream = response.GetResponseStream(); StreamReader reader = new StreamReader(dataStream); result = reader.ReadToEnd(); reader.End(); response.End(); }

Hi Subbarao, Many many thanks but reader and datastream does not have .End() method. It shows error.

Hi In your code change the reader.Close() to reader.End(). using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { Stream dataStream = response.GetResponseStream(); StreamReader reader = new StreamReader(dataStream); result = reader.ReadToEnd(); reader.End(); dataStream.End(); }

Hi, Thanks for you help. Can you integrate this into the code above. Actually, I don't have much knowledge about it.

Hi you can use response.end instead of close. https://www.c-sharpcorner.com/forums/difference-between-responseclose-and-responseend
