Pass more than one url to httpwebrequest.create method

Question

Hi all I am trying to display tweets from multiple users at the same time. I tried storing the urls in an array then looping through the array to get the urls and send them to  timeLineRequest = (HttpWebRequest)WebRequest.Create(urls); but it only stores the last url. I am using a foreach for this. What am I doing wrong? Coding in c# Thanks in advance

Thanks again your answer gave me an idea: I created a list of objects outside the foreach then inside the foreach I add the timeLineJson object to the list and return the list instead if just the one object. List timelines = new List (); //inside foreach as last line: timelines.Add(timeLineJson); then for the return statement: return Json(timelines JsonRequestBehavior.AllowGet); Hope this helps someone Now I need to figure out how to slice this List to render properly using .getJSon

Thnks Dhirendra but your last line gives me an error ....has some invalid arguments

From your code is clear that your overwriting the variable timeLineResponse within foreach. That is why last value is being persisted. You need to create collection of timeLineResponse and try to extract the data from each stored value in the collection. Collection can be prepared using List within foreach {} List listTimeLineResponse = new List (); timeLineResponse = (HttpWebResponse)timeLineRequest.GetResponse(); listTimeLineResponse.Add(timeLineResponse);

Here is the code: twitterHandle = new string[2]; twitterHandle[0] = https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=PretoriaRSA&count=5&trim_user=true&include_rts=false&include_entities=false; twitterHandle[1] = https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=DebonairsPizza&count=5&trim_user=true&include_rts=false&include_entities=false; foreach (string t in twitterHandle) { timeLineRequest = (HttpWebRequest)WebRequest.Create(t); var timelineHeaderFormat = {0} {1}; timeLineRequest.Headers.Add(Authorization string.Format(timelineHeaderFormat twitAuthResponse.token_type twitAuthResponse.access_token)); timeLineRequest.Method = Get; timeLineRequest.ContentType = application/json; charset=utf-8; timeLineResponse = timeLineRequest.GetResponse(); } using (timeLineResponse) { using (var reader = new StreamReader(timeLineResponse.GetResponseStream())) { JavaScriptSerializer js = new JavaScriptSerializer(); timeLineJson = js.Deserialize (reader.ReadToEnd()); } } return Json(timeLineJson JsonRequestBehavior.AllowGet); I only get statuses for DebonairsPizza

Hello Avuya I am not sure I am getting you properly. Are you getting value of variable timeLineRequest is as last URL because you are overwriting the value of variable timeLineRequest in the loop. Hence the last URL value your are getting in variable when foreach exits. I tried the same and I got output: HttpWebRequest timeLineRequest; string[] arrUrls = { http://www.google.com http://www.contoso.com/default.html http://www.msn.com }; foreach (string url in arrUrls) { timeLineRequest = (HttpWebRequest)WebRequest.Create(url); Console.WriteLine(timeLineRequest.Host); } Output: www.google.com www.contoso.com www.msn.com

Its just a string array where I say index 0 = one url and index 1 is the other. then I loop through them using foreach. It gets the first url and passes it to the timeLineRequest = (HttpWebRequest)WebRequest.Create(urls) gets the second one and does the same. but when it goes out of the foreach it only returns the last url

Hello Avuya Please share the piece of code where you are storing the URLs in an array I think there will be some issue. Thanks
