Reading lines of GetResponseStream

Hey all,

I'm using the following to GET web pages:

Dim request As HttpWebRequest = DirectCast(WebRequest.Create(url), HttpWebRequest)
request.CookieContainer = logincookie
Dim response As HttpWebResponse = DirectCast(request.GetResponse(), HttpWebResponse)
Dim reader As New StreamReader(response.GetResponseStream())
Dim thesource As String = reader.ReadToEnd

I'm trying to extract data from the source. thesource holds the source code of the page successfully, however, I can't loop through each line using a For Each loop, as it merely responds with each character instead of each line.

Can somebody suggest how to fix this?
Thanks guys, Stan.
