C#實現office文檔轉換為PDF或xps

需要安裝office 2007 還有一個office2007的外掛程式OfficeSaveAsPDFandXPShttp://www.microsoft.com/downloads/details.aspx?FamilyId=4D951911-3E7E-4AE6-B059-A2E79ED87041&displaylang=en這是一個微軟官方出的office外掛程式。如果無法下載，可以下載我的：http://files.cnblogs.com/kaixing/SaveAsPDFandXPS.zip 

安裝wps後，也支援wps格式

 首先添加以下com組件的引用

Microsoft Word 12.0 Object LibraryMicrosoft PowerPoint 12.0 Object LibraryMicrosoft Excel 12.0 Object Library ------------------------------------------------------程式中：using Word = Microsoft.Office.Interop.Word;
using Excel = Microsoft.Office.Interop.Excel;
using PowerPoint = Microsoft.Office.Interop.PowerPoint;using Microsoft.Office.Core; 1.word轉換方法private bool Convert(string sourcePath, string targetPath, Word.WdExportFormat exportFormat)
        {
            bool result;
            object paramMissing = Type.Missing;　　　　//這裡會報錯，提示無法嵌入........   解決方案在下面
            Word.ApplicationClass wordApplication = new Word.ApplicationClass();
            Word.Document wordDocument = null;
            try
            {
                object paramSourceDocPath = sourcePath;
                string paramExportFilePath = targetPath;

                Word.WdExportFormat paramExportFormat = exportFormat;
                bool paramOpenAfterExport = false;
                Word.WdExportOptimizeFor paramExportOptimizeFor =
                        Word.WdExportOptimizeFor.wdExportOptimizeForPrint;
                Word.WdExportRange paramExportRange = Word.WdExportRange.wdExportAllDocument;
                int paramStartPage = 0;
                int paramEndPage = 0;
                Word.WdExportItem paramExportItem = Word.WdExportItem.wdExportDocumentContent;
                bool paramIncludeDocProps = true;
                bool paramKeepIRM = true;
                Word.WdExportCreateBookmarks paramCreateBookmarks =
                        Word.WdExportCreateBookmarks.wdExportCreateWordBookmarks;
                bool paramDocStructureTags = true;
                bool paramBitmapMissingFonts = true;
                bool paramUseISO19005_1 = false;

                wordDocument = wordApplication.Documents.Open(
                        ref paramSourceDocPath, ref paramMissing, ref paramMissing,
                        ref paramMissing, ref paramMissing, ref paramMissing,
                        ref paramMissing, ref paramMissing, ref paramMissing,
                        ref paramMissing, ref paramMissing, ref paramMissing,
                        ref paramMissing, ref paramMissing, ref paramMissing,
                        ref paramMissing);

                if (wordDocument != null)

　　　　　　　　　//定義的很多屬性，大家可以去查下手冊ExportAsFixedFormat；
                    wordDocument.ExportAsFixedFormat(paramExportFilePath,
                            paramExportFormat, paramOpenAfterExport,
                            paramExportOptimizeFor, paramExportRange, paramStartPage,
                            paramEndPage, paramExportItem, paramIncludeDocProps,
                            paramKeepIRM, paramCreateBookmarks, paramDocStructureTags,
                            paramBitmapMissingFonts, paramUseISO19005_1,
                            ref paramMissing);
                result = true;
            }
            finally
            {
                if (wordDocument != null)
                {
                    wordDocument.Close(ref paramMissing, ref paramMissing, ref paramMissing);
                    wordDocument = null;
                }
                if (wordApplication != null)
                {
                    wordApplication.Quit(ref paramMissing, ref paramMissing, ref paramMissing);
                    wordApplication = null;
                }
                GC.Collect();
                GC.WaitForPendingFinalizers();
                GC.Collect();
                GC.WaitForPendingFinalizers();
            }
            return result;
        }解決方案：

　　　　　　　　修改你添加的引用的屬性，將類型改為false大家可以使用我前面的上傳的代碼，簡單的實驗使用方法： Convert(sourcePath, targetPath, Word.WdExportFormat.wdExportFormatPDF);sourcePath為你上次檔案路徑..如：D:\project\UpLoadFile\UpLoadFile\files\123.docxtargetPath為你裝換檔案路徑..如：D:\project\UpLoadFile\UpLoadFile\files\123.pdfWord.WdExportFormat.wdExportFormatPDF為轉換的格式 //Excel轉換方法
        private bool ExcelConvert(string sourcePath, string targetPath, Excel.XlFixedFormatType targetType)
        {
            bool result;
            object missing = Type.Missing;
            Excel.ApplicationClass application = null;
            Excel.Workbook workBook = null;
            try
            {
                application = new Excel.ApplicationClass();
                object target = targetPath;
                object type = targetType;
                workBook = application.Workbooks.Open(sourcePath, missing, missing, missing, missing, missing,
                        missing, missing, missing, missing, missing, missing, missing, missing, missing);

                workBook.ExportAsFixedFormat(targetType, target, Excel.XlFixedFormatQuality.xlQualityStandard, true, false, missing, missing, missing, missing);
                result = true;
            }
            catch
            {
                result = false;
            }
            finally
            {
                if (workBook != null)
                {
                    workBook.Close(true, missing, missing);
                    workBook = null;
                }
                if (application != null)
                {
                    application.Quit();
                    application = null;
                }
                GC.Collect();
                GC.WaitForPendingFinalizers();
                GC.Collect();
                GC.WaitForPendingFinalizers();
            }
            return result;
        }

        //PowerPoint轉換方法
        private bool PowerPointConvert(string sourcePath, string targetPath, PowerPoint.PpSaveAsFileType targetFileType)
        {
            bool result;
            object missing = Type.Missing;
            PowerPoint.ApplicationClass application = null;
            PowerPoint.Presentation persentation = null;
            try
            {
                application = new PowerPoint.ApplicationClass();
                persentation = application.Presentations.Open(sourcePath, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoFalse);
                persentation.SaveAs(targetPath, targetFileType, Microsoft.Office.Core.MsoTriState.msoTrue);

                result = true;
            }
            catch
            {
                result = false;
            }
            finally
            {
                if (persentation != null)
                {
                    persentation.Close();
                    persentation = null;
                }
                if (application != null)
                {
                    application.Quit();
                    application = null;
                }
                GC.Collect();
                GC.WaitForPendingFinalizers();
                GC.Collect();
                GC.WaitForPendingFinalizers();
            }
            return result;
