How to use HttpWebRequest to download file

Trying to download file in code.  
Current code:
  Dim uri As New UriBuilder
    uri.UserName = "xxx"
    uri.Password = "xxx"
    uri.Host = "xxx"
    uri.Path = "xxx.aspx?q=65"

   Dim request As HttpWebRequest = DirectCast(WebRequest.Create(uri.Uri), HttpWebRequest)

    request.AllowAutoRedirect = True

    request = DirectCast(WebRequest.Create(DownloadUrlIn), HttpWebRequest)
    request.Timeout = 10000
    'request.AllowWriteStreamBuffering = True

    Dim response As HttpWebResponse = Nothing
    response = DirectCast(request.GetResponse(), HttpWebResponse)
    Dim s As Stream = response.GetResponseStream()

    'Write to disk
    Dim fs As New FileStream("c:\xxx.pdf", FileMode.Create)

    Dim read As Byte() = New Byte(255) {}
    Dim count As Integer = s.Read(read, 0, read.Length)
    While count > 0
        fs.Write(read, 0, count)
        count = s.Read(read, 0, read.Length)
    End While

    'Close everything
    fs.Close()
    s.Close()
    response.Close()

Running this code and checking the response.ResponseUri indicates im being redirected back to the login page and not to the pdf file.  
For some reason its not authorising access what could I be missing as Im sending the user name and password in the uri? Thanks for your help

A:

You don't need all of that code to download a file from the net
just use the WebClient class and its DownloadFile method
