1.word转换方法

private bool Convert(string sourcePath, string targetPath, Word.WdExportFormat exportFormat)

        {

            bool result;

            object paramMissing = Type.Missing;

　　　　//这里会报错，提示无法嵌入........   解决方法在下面

            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)

　　　　　　　　　//定义的很多属性，大家可以去查下手册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;

        }

解决方法：

　　　　

　　　　修改你添加的引用的属性，将类型改为false

大家可以使用我前面的上传的代码，简单的试验

使用方法： Convert(sourcePath, targetPath, Word.WdExportFormat.wdExportFormatPDF);

sourcePath为你上次文件路径..如：D:\project\UpLoadFile\UpLoadFile\files\123.docx

targetPath为你装换文件路径..如：D:\project\UpLoadFile\UpLoadFile\files\123.pdf

Word.WdExportFormat.wdExportFormatPDF为转换的格式

 

//Excel转换方法

        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转换方法

        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;

        }
