[HELP] Proxy with HttpWebRequests?

So my current code is

Code:

  Try
    Dim WR As Net.HttpWebRequest = Net.HttpWebRequest.Create(TextBox1.Text)
    Dim Response As Net.HttpWebResponse = WR.GetResponse()
    Dim SR As New IO.StreamReader(Response.GetResponseStream)
    Dim PageData As String = SR.ReadToEnd()
    SR.Close()
  Catch ex As Exception
    Dim WR As Net.HttpWebRequest = Net.HttpWebRequest.Create("http://" & TextBox1.Text)
    Dim Response As Net.HttpWebResponse = WR.GetResponse()
    Dim SR As New IO.StreamReader(Response.GetResponseStream)
    Dim PageData As String = SR.ReadToEnd()
    SR.Close()
  End Try

How can I use proxies with a webrequest?

I know how to do it with webpages. I use the RefreshIEsettings, but how do i do it with webrequests?

 

There is an HttpWebRequest.Proxy field. Take a look at http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.proxy.aspx
