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
