WPF:您如何在横向模式下打印？

Question

找到 this function在线，效果很好......除了我不知道如何将它默认为横向打印。

private void PrintClick(object sender, RoutedEventArgs e)
{
  PrintDialog dialog = new PrintDialog();
  if (dialog.ShowDialog() == true)
  { dialog.PrintVisual(_PrintCanvas, "My Canvas"); }
}

实际上如何设置默认值以将我的 wpf 内容打印为横向模式？

编辑:固定变量名称，由@SHIN JaeGuk 提及

private void PrintClick(object sender, RoutedEventArgs e)
{
    PrintDialog dialog = new PrintDialog();
    if (dialog.ShowDialog() == true)
    { 
        //Set PageOrientation to Landscape
        dialog.PrintTicket.PageOrientation = PageOrientation.Landscape;
        dialog.PrintVisual(_PrintCanvas, "My Canvas"); 
    }
}
