{
    FileStream fs = null;

    try
    {
        fs = new FileStream(inkFileName, FileMode.Create);
        inkCanvas1.Strokes.Save(fs);
    }
    finally
    {
        if (fs != null)
        {
            fs.Close();
        }
    }
}


...


private void LoadStrokes_Click(object sender, RoutedEventArgs e)
{
    FileStream fs = null;

    if (!File.Exists(inkFileName))
    {
        MessageBox.Show("The file you requested does not exist." +
            " Save the StrokeCollection before loading it.");
        return;
    }

    try
    {
        fs = new FileStream(inkFileName,
            FileMode.Open, FileAccess.Read);
        StrokeCollection strokes = new StrokeCollection(fs);
        inkCanvas1.Strokes = strokes;
    }
    finally
    {
        if (fs != null)
        {
            fs.Close();
        }
    }

}
