在 c# 中将 RTF 文件转换为 PDF

我需要提供将RTF/WORD文件转换为PDF并将其作为附件发送到电子邮件的功能，为此我尝试了如下所示的代码：

    // Create a new Microsoft Word application object
    Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application();
    // C# doesn't have optional arguments so we'll need a dummy value
    object oMissing = System.Reflection.Missing.Value;
    Document doc;
    protected void Page_Load(object sender, EventArgs e)
    {
        ConvertToPDF("test.doc");
    }
    void ConvertToPDF(string sFileName)
    {
        // Create a new Microsoft Word application object
        Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application();
        // C# doesn't have optional arguments so we'll need a dummy value
        object oMissing = System.Reflection.Missing.Value;
        Document doc;
        try
        {
            word.Visible = false;
            word.ScreenUpdating = false;
            DirectoryInfo dirInfo = new DirectoryInfo(Server.MapPath(".") + "''TempDoc");
            FileInfo[] wordFile = dirInfo.GetFiles(sFileName);
            if (wordFile.Length > 0)
            {
                Object filename = (Object)wordFile[0].FullName;
                // Use the dummy value as a placeholder for optional arguments
                doc = word.Documents.Open2000(ref filename, ref oMissing,
                    ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                    ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing);
                doc.Activate();
                object outputFileName = wordFile[0].FullName.Replace(".doc", "");
                object fileFormat = WdSaveFormat.wdFormatPDF;
                // Save document into PDF Formats
                doc.SaveAs2000(ref outputFileName, ref fileFormat, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing);
            }
        }
        catch (Exception ex)
        {
            Response.Write(ex);
        }
        finally
        {
            // Close the Word document, but leave the Word application open.
            // doc has to be cast to type _Document so that it will find the
            // correct Close method.
            doc = null;
            // word has to be cast to type _Application so that it will find
            // the correct Quit method.
            word = null;
        }
    }

但它给出了错误.doc。SaveAs2000（ref output文件名， ref fileFormat， ref oMissing， ref oMissing， ref oMissing， ref oMissing， ref oMissing， ref oMissing， ref oMissing， ref oMissing， ref oMissing， ref oMissing）;陈述。

这可能是我们有Microsoft Office 2007的原因，在这种情况下，没有任何选项可以另存为PDF文件。在Microsoft Office 2010 中，它具有该选项，因此当服务器上安装 Office 2010 时Microsoft此代码可能有效。

是的，它在 2010 年确实有效。我最近用过它，但我相信 2007 年有一个补丁也添加了另存为 PDF 功能

也许试试这个 http://msdn.microsoft.com/en-us/library/bb412305（v=office.12）.aspx

 Microsoft.Office.Interop.Word.Application appWord = new Microsoft.Office.Interop.Word.Application();
        appWord.Visible = false;
        //object oMissing = Type.Missing;
        object oMissing = System.Reflection.Missing.Value;
        // Declare variables for the Document.ExportAsFixedFormat method parameters.
        bool paramOpenAfterExport = false;
        Office.WdExportOptimizeFor paramExportOptimizeFor =
        Office.WdExportOptimizeFor.wdExportOptimizeForOnScreen;
        Office.WdExportRange paramExportRange = Office.WdExportRange.wdExportAllDocument;
        int paramStartPage = 0;
        int paramEndPage = 0;
        Office.WdExportItem paramExportItem = Office.WdExportItem.wdExportDocumentWithMarkup; //This is 
        //the key to keep track changes markup;
        bool paramIncludeDocProps = true;
        bool paramKeepIRM = true;
        Office.WdExportCreateBookmarks paramCreateBookmarks =
                    Office.WdExportCreateBookmarks.wdExportCreateWordBookmarks;
        bool paramDocStructureTags = true;
        bool paramBitmapMissingFonts = true;
        bool paramUseISO19005_1 = false;
        Microsoft.Office.Interop.Word.Document wordDocument = appWord.Documents.Open(fileToProcess);
        wordDocument.ExportAsFixedFormat(tempPDFFilePath, Office.WdExportFormat.wdExportFormatPDF, paramOpenAfterExport, paramExportOptimizeFor, paramExportRange, paramStartPage, paramEndPage, paramExportItem,
        paramIncludeDocProps, paramKeepIRM, paramCreateBookmarks, paramDocStructureTags, paramBitmapMissingFonts, paramUseISO19005_1, ref oMissing);
        ((Office._Document)wordDocument).Close(false, Type.Missing, Type.Missing);
        ((Office._Application)appWord).Quit(false);

首先需要从 nugget 包中添加 Microsoft.Office.Interop.dll。将.rft原始文件添加为文件到处理，并在tempFilePath中添加需要保存转换后的pdf文件的位置路径。
