C# 为什么在使用xlDialogPrint.Show方法时，在c中获取Dialog类的Show方法失败？

我正在尝试使用visual studio以C语言打印Microsoft Excel文档，每次尝试执行这段代码时，我都会得到一个对话框类失败异常的显示方法：

bool userDidntCancel =
       ExcelApp.Dialogs[Excel.XlBuiltInDialog.xlDialogPrint].Show(
           Type.Missing, Type.Missing, Type.Missing, Type.Missing,Type.Missing,
           Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
           Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
           Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
           Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
           Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

以下是我使用的完整代码：

            Excel.Application ExcelApp = new Excel.Application();

            Excel.Workbook wb = ExcelApp.Workbooks.Open(
            PATH,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
            Type.Missing, Type.Missing, Type.Missing, Type.Missing);

            Excel.Worksheet ws = (Excel.Worksheet)wb.Worksheets[1];

    try
    {
        bool userDidntCancel =
           ExcelApp.Dialogs[Excel.XlBuiltInDialog.xlDialogPrint].Show(
               Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
               Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
               Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
               Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
               Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
               Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
    }
    catch
    {
        ExcelApp.Quit();
        File.Delete("Container Status.xls");
    }

有什么东西我遗漏了吗？

你搜索了1秒钟吗？是的，事实上我找到了，但没有找到答案。你发布链接的代码甚至不是一回事！我使用的XLDialogPrintBox不仅仅是一种打印输出方法，还感谢您的点评。
