c# - 如何在转换为PDF时保持word文档的字体属性

Question

我在将 Word 文档转换为 PDF 时遇到问题。在我的word文档中，字体是这样的(Times New Roman):

但是当转换为 PDF 时，它变成了:

我使用了以下代码:

        Word._Application oWord = new Word.Application();

        // Make this instance of word invisible (Can still see it in the taskmgr).
        oWord.Visible = false;

        // Interop requires objects.
        object oMissing = System.Reflection.Missing.Value;
        object isVisible = true;
        object readOnly = false;
        object oInput = Application.StartupPath+"\file.docx";
        object oOutput = Application.StartupPath+"\file.docx".Replace(".docx", ".pdf");
        object oFormat = Word.WdSaveFormat.wdFormatPDF;

        // Load a document into our instance of word.exe
        Word._Document oDoc = oWord.Documents.Open(ref oInput, ref oMissing, ref readOnly, 
            ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, 
            ref oMissing, ref oMissing, ref isVisible, ref oMissing, ref oMissing, ref oMissing, ref oMissing);

        // Make this document the active document.
        oDoc.Activate();

        // Save this document in Word 2003 format.
        oDoc.SaveAs(ref oOutput, ref oFormat, ref oMissing, ref oMissing, ref oMissing,
            ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
            ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing);

        // Always close Word.exe.
        oWord.Quit(ref oMissing, ref oMissing, ref oMissing);

如何将 word 文档转换为 PDF 并保持其字体属性？

我最近遇到了类似的问题。我的字体不会更改，但其他 Word 格式元素在使用 Word.Interop SaveAs 方法时会丢失/更改。这是我用来为我解决问题的方法。我下面的示例使用应用程序和文档，而不是您的 _Application 和 _Document。我不熟悉它们之间的差异，但认为它应该适用于任何一种方法。

bool _OpenAfterExport = false;
bool _KeepIRM = true;
int _From = 1;
int _To = 1; //I thought this was odd, setting From and To to 1, but it exported all pages of the document
bool _IncludeDocProps = true;

Word.Document oDoc = oWord.Documents.Open(inputFile);
oDoc.ExportAsFixedFormat(outputFile,
                         Word.WdExportFormat.wdExportFormatPDF,
                         OpenAfterExport,
                         Word.WdExportOptimizeFor.wdExportOptimizeForPrint,
                         Word.WdExportRange.wdExportAllDocument,
                         _From,
                         _To,
                         Word.WdExportItem.wdExportDocumentContent,
                         _IncludeDocProps,
                         _KeepIRM,
                         Word.WdExportCreateBookmarks.wdExportCreateHeadingBookmarks)
oDoc.Close();
oWord.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(oDoc);

希望这能解决您的问题。
