    }
    foreach(string prefix in prefixes)
    {
        Console.WriteLine(prefix);
    }
    // Show the listening state.
    if (listener.IsListening)
    {
        Console.WriteLine("The server is listening.");
    }
}

Public Shared Sub DisplayPrefixesAndState(ByVal listener As HttpListener)
    ' List the prefixes to which the server listens.
    Dim prefixes As HttpListenerPrefixCollection = listener.Prefixes

    If prefixes.Count = 0 Then
        Console.WriteLine("There are no prefixes.")
    End If

    For Each prefix As String In prefixes
        Console.WriteLine(prefix)
    Next

    ' Show the listening state.

        Console.WriteLine("The server is listening.")
    End If
End Sub
