Excel ExportAsFixedFormat PDF

Question

我可以成功获取excel文件并将其作为PDF文件导出到c#中

private static void ExportWorkbookToPDF(string workbook, string output)
{
    if (string.IsNullOrEmpty(workbook) || string.IsNullOrEmpty(output))
    {
        throw new NullReferenceException("Cannot create PDF copy " +
            "from empty workbook.");
    }

    Application excelApplication = new Application();
    excelApplication.ScreenUpdating = false;
    excelApplication.DisplayAlerts = false;
    excelApplication.Visible = false;

    Workbook excelWorkbook = excelApplication.Workbooks.Open(
        Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + 
        "\\" + workbook);

    if (excelWorkbook == null)
    {
        excelApplication.Quit();
        excelApplication = null;
        excelWorkbook = null;

        throw new NullReferenceException("Cannot create new excel workbook.");
    }

    try
    {
        excelWorkbook.ExportAsFixedFormat(XlFixedFormatType.xlTypePDF, 
            Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + 
            "\\" + output);
    }
    catch (Exception e)
    {
        Console.WriteLine(e.Message);
        Console.ReadLine();
    }
    finally
    {
        excelWorkbook.Close();
        excelApplication.Quit();
        excelApplication = null;
        excelWorkbook = null;
    }
}

我需要访问什么参数或对象才能将excel文件保存为页面宽度而不是页面高度？

我找到了强制导出工作簿所需的属性在带有横向视图的PDF中.

try 
{ 
    ((Microsoft.Office.Interop.Excel._Worksheet)  
    excelWorkbook.ActiveSheet).PageSetup.Orientation =  
    Microsoft.Office.Interop.Excel.XlPageOrientation.xlLandscape;

    excelWorkbook.ExportAsFixedFormat(XlFixedFormatType.xlTypePDF,  
    Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + 
        "\\" + output); 
}
