private Microsoft.Office.Interop.Word.ApplicationClass MSdoc;       

        //Use for the parameter whose type are not known or say Missing
        object Unknown = Type.Missing;

  private void word2PDF(object Source, object Target)
        {   //Creating the instance of Word Application          
       if (MSdoc == null)MSdoc = new Microsoft.Office.Interop.Word.ApplicationClass();

            try
            {  
                MSdoc.Visible = false;               
                MSdoc.Documents.Open(ref Source, ref Unknown,
                     ref Unknown, ref Unknown, ref Unknown,
                     ref Unknown, ref Unknown, ref Unknown,
                     ref Unknown, ref Unknown, ref Unknown,
                     ref Unknown, ref Unknown, ref Unknown, ref Unknown, ref Unknown);
                MSdoc.Application.Visible = false;
                MSdoc.WindowState = Microsoft.Office.Interop.Word.WdWindowState.wdWindowStateMinimize;               

                object format = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatPDF;

                MSdoc.ActiveDocument.SaveAs(ref Target, ref format,
                        ref Unknown, ref Unknown, ref Unknown,
                        ref Unknown, ref Unknown, ref Unknown,
                        ref Unknown, ref Unknown, ref Unknown,
                        ref Unknown, ref Unknown, ref Unknown,
                       ref Unknown, ref Unknown);
            }
            catch (Exception e)
            {
                MessageBox.Show(e.Message);
            }
            finally
            {
                if (MSdoc != null)
                {
                    MSdoc.Documents.Close(ref Unknown, ref Unknown, ref Unknown);
                    //WordDoc.Application.Quit(ref Unknown, ref Unknown, ref Unknown);
                }               
                // for closing the application
                WordDoc.Quit(ref Unknown, ref Unknown, ref Unknown);
            }
        }

先决条件：

• MS word2007 与（默认安装主要互操作性程序集）。
• 插件SaveAsPDFandXPS（从 MS Site 免费）

确保您参考了 Word.12。它会自动将 Microsoft.Office.interop.word 添加到您的参考中。按照这些进行其他办公应用程序。（注意：您应该已安装 VS 2005 Tools for Office 2nd Ed. Runtime (VSTO 2005 SE) (x86)

//Add Office Library

using Word = Microsoft.Office.Interop.Word;

object str_letter_path = @"D:\DOCTEST.doc";
object outputFilePathPDF = @"D:\PDFTEST.PDF";

Word.Application wordApp = new Word.Application();
wordApp.Visible = false;
wordApp.ScreenUpdating = false;

object oMissing = System.Reflection.Missing.Value;
object fileFormat = Word.WdSaveFormat.wdFormatPDF;

Word.Document doc = wordApp.Documents.Open(ref str_letter_path, 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, ref oMissing);

            doc.Activate();

            doc.SaveAs(ref outputFilePathPDF,
                            ref fileFormat, 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);

            object saveChanges = Word.WdSaveOptions.wdDoNotSaveChanges;
            if (doc != null)
                ((Word._Document)doc).Close(ref saveChanges, ref oMissing, ref oMissing);
            ((Microsoft.Office.Interop.Word._Application)wordApp).Quit(ref saveChanges, ref oMissing, ref oMissing);

Answer 3

您可以使用Microsoft.Office.Interop.Word.dll将 Word 文件转换为 PDF。

首先安装包并添加对它的引用。

using Microsoft.Office.Interop.Word;

然后使用以下代码将 word 文档转换为 PDF。

Application app = new Application();
Document doc = app.Documents.Open(@"D:/test.docx");
doc.SaveAs2(@"D:/test.pdf", WdSaveFormat.wdFormatPDF);
doc.Close();
app.Quit();
Console.WriteLine("Completed");

Answer 4

您可以使用我的代码，它可以正常工作，并且不会在后台进程中保留打开的 COM 对象。

Application app = new Application();
                app.Visible = false;
                app.DisplayAlerts = WdAlertLevel.wdAlertsNone;
                Documents documents = app.Documents;
                Document doc = documents.Open(fileLocation);
                newPath = Path.GetDirectoryName(fileLocation);
                newPath = newPath.Replace(newPath, outLocation);
                if (!File.Exists(newPath))
                {
                    doc.SaveAs2(newPath, WdSaveFormat.wdFormatPDF);
                }

                Marshal.ReleaseComObject(documents);
                doc.Close();
                Marshal.ReleaseComObject(doc);
                app.Quit();
                Marshal.ReleaseComObject(app);
