Read one proxy from textfile every 5 times

Hello guys. I have a little problem.

I have this class:

Code:

---

Public Class ProxyHelper
    Private Shared proxyQueue As New Queue(Of System.Net.WebProxy)()
    ' Just holds the number of times we've asked for a proxy.
    Private Shared proxyUses As Integer

    Public Shared Sub AddProxy(ByVal proxy As System.Net.WebProxy)
        proxyQueue.Enqueue(proxy)
    End Sub

    Public Shared Sub AddProxy(ByVal proxy As String)
        proxyQueue.Enqueue(New System.Net.WebProxy(proxy))
    End Sub

    Public Shared ReadOnly Property Count() As Integer
        Get
            Return proxyQueue.Count
        End Get
    End Property

    Public Shared Function GetProxy() As System.Net.WebProxy
        proxyUses += 1
        If proxyUses Mod 5 = 0 Then
            proxyQueue.Dequeue()
        End If
        Return proxyQueue.Peek()
    End Function
End Class

This will ask for one proxy each time my webclient does something five times.

My webclient simply downloads some data and views it from a webpage over and over, and after 5 times you will get banned.

Question: How can I make the above code ask for a proxy from a textfile with one proxy on each line?

I will not have a browse function, the proxies.txt will always be in the app.dir


Thanks
