int historySize =
    sessionPageState.HistorySize;

string msg = String.Format(
"Current history size: {0}\n",
historySize.ToString());

Console.Write(msg);

if (!sessionPageState.IsReadOnly())
{
    // Double current history size.
    sessionPageState.HistorySize =
        2 * sessionPageState.HistorySize;

    configuration.Save();

    historySize =
        sessionPageState.HistorySize;

    msg = String.Format(
    "New history size: {0}\n",
    historySize.ToString());

    Console.Write(msg);
}

' Get the history size.
Dim historySize As Integer = _
sessionPageState.HistorySize

Dim msg As String = _
String.Format( _
"Current history size: {0}" + _
ControlChars.Lf, historySize.ToString())

Console.Write(msg)


If Not sessionPageState.IsReadOnly() Then
    ' Double current history size.
    sessionPageState.HistorySize = _
    2 * sessionPageState.HistorySize

    configuration.Save()

    historySize = sessionPageState.HistorySize

    msg = String.Format( _
    "New history size: {0}" + _
    ControlChars.Lf, historySize.ToString())

    Console.Write(msg)
End If
