windows - 以编程方式使用 Microsoft XPS Document Writer 创建 XPS 文件

Question

我正在研究批量打印解决方案。

要打印的文件将采用各种（典型）格式，例如 PDF、Word、Excel 等。从我收集（和测试）的内容来看，打印 XPS 文件是在 Windows 平台上进行的方式。

但是，我完全不清楚如何实际创建 XPS 文件 - 没有深入了解相关输入文件格式（即以编程方式）。

我希望我可以打印到本地Microsoft XPS Document Writer “打印机”，然后物理打印其输出（即 XPS 文件）。

我无法以编程方式成功地做到这一点。我试过托管代码System.Printing、非托管代码Winspool API。

我可以成功打开打印机并将原始数据写入其中，但我从未得到 XPS 文件输出。如何创建 XPS 文件？我查看了XPSDocumentWriterAPI，但这似乎非常复杂，并且可能已经由Microsoft XPS Document Writer和/或现有应用程序实现。

我发现一种方法是从创建文档的应用程序开始，即。Word、Excel 等并使其打印。这段代码将一个字符串带入要转换的文档，在用户 %tmp% 文件夹中创建一个 xps 文件并将该字符串返回给文档。它可以完成这项工作，但速度并不快：

    private readonly string TEMP = Environment.ExpandEnvironmentVariables("%tmp%");
    private  object nullObject = Type.Missing;

    private string ConvertWordtoXps(string wordDocName)
    {
        Microsoft.Office.Interop.Word.Application wordApp = new Microsoft.Office.Interop.Word.Application();
        wordApp.Documents.Open(wordDocName, ConfirmConversions: false, ReadOnly: true);
        string xpsFileName = String.Concat(TEMP, "\\", Path.GetFileNameWithoutExtension(wordDocName), ".xps");

        try
        {
            wordApp.ActiveDocument.SaveAs2(xpsFileName, FileFormat: WdSaveFormat.wdFormatXPS);
            return xpsFileName;
        }
        catch (Exception e)
        {
            MessageBox.Show(e.Message);
        }
        finally
        {
            ((Microsoft.Office.Interop.Word._Application)wordApp).Quit(SaveChanges: false, OriginalFormat: nullObject, RouteDocument: nullObject);
        }
        return null;

    }

    private string ConvertExceltoXps(string excelWorkbookName)
    {
        Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
        excelApp.Workbooks.Add(excelWorkbookName);
        Workbook excelWorkbook = excelApp.ActiveWorkbook;
        string xpsFileName = String.Concat(TEMP, "\\", Path.GetFileNameWithoutExtension(excelWorkbookName), ".xps");

        try
        {
            excelWorkbook.ExportAsFixedFormat(
                XlFixedFormatType.xlTypeXPS,
                xpsFileName,  
                Quality: XlFixedFormatQuality.xlQualityMinimum,
                IncludeDocProperties: false,
                IgnorePrintAreas: false,
                From: nullObject,
                To: nullObject,
                OpenAfterPublish: false,
                FixedFormatExtClassPtr: nullObject
            );

            return xpsFileName;
        }
        catch (Exception e)
        {
            MessageBox.Show(e.Message);
        }
        finally
        {
            excelWorkbook.Close(XlSaveAction.xlDoNotSaveChanges, Filename: nullObject, RouteWorkbook: nullObject); 
            ((Microsoft.Office.Interop.Excel._Application)excelApp).Quit();
        }
        return null;
    }

    private string ConvertPowerPointtoXps(string pptFile)
    {
        Microsoft.Office.Interop.PowerPoint.Application pptApp = new Microsoft.Office.Interop.PowerPoint.Application();
        Microsoft.Office.Interop.PowerPoint.Presentations pptSet = pptApp.Presentations;
        Microsoft.Office.Interop.PowerPoint.Presentation pptPresentation = pptSet.Open(pptFile, ReadOnly: MsoTriState.msoTrue, Untitled: MsoTriState.msoTrue, WithWindow: MsoTriState.msoFalse);
        string xpsFileName = String.Concat(TEMP, "\\", Path.GetFileNameWithoutExtension(pptFile), ".xps");

        try
        {
            pptPresentation.ExportAsFixedFormat(
                xpsFileName,
                PpFixedFormatType.ppFixedFormatTypeXPS,
                PpFixedFormatIntent.ppFixedFormatIntentScreen,

        catch (Exception e)
        {
            MessageBox.Show(e.Message);
        }
        finally

            ((Microsoft.Office.Interop.PowerPoint._Application)pptApp).Quit();
        }
        return null;
