1.首先上网搜索一下有什么解决方案 （1）.将文档转换为html，只支持支持office文档 （2）.将文档转换为flash,实现类似百度文库的效果，除支持office文档外还支持pdf
（1） a.首先添加引用:
using Microsoft.Office.Core;using Word = Microsoft.Office.Interop.Word;
b.其次编写文档转换的方法:
1 /// <summary> 2 /// word转成html 3 /// </summary> 4 /// <param name="path">要转换的文档的路径</param> 5 /// <param name="savePath">转换成的html的保存路径</param> 6 /// <param name="wordFileName">转换后html文件的名字</param> 7 private static void WordToHtml(string path, string savePath, string wordFileName) 8 { 9 Word.ApplicationClass word = new Word.ApplicationClass();10 Type wordType = word.GetType();11 Word.Documents docs = word.Documents;12 Type docsType = docs.GetType();13 Word.Document doc = (Word.Document)docsType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] {(object)path, true, true });14 Type docType = doc.GetType();15 string strSaveFileName = savePath + wordFileName + ".html";16 object saveFileName = (object)strSaveFileName;17 docType.InvokeMember("SaveAs", System.Reflection.BindingFlags.InvokeMethod, null, doc, new object[] { saveFileName, Word.WdSaveFormat.wdFormatFilteredHTML });18 docType.InvokeMember("Close", System.Reflection.BindingFlags.InvokeMethod, null, doc, null);19 wordType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod, null, word, null);20 }21 /// <summary>22 /// excel 转换为html23 /// </summary>24 /// <param name="path">要转换的文档的路径</param>25 /// <param name="savePath">转换成的html的保存路径</param>26 /// <param name="wordFileName">转换后html文件的名字</param>27 public static void ExcelToHtml(string path, string savePath, string wordFileName)28 {29 string str = string.Empty;30 Microsoft.Office.Interop.Excel.Application repExcel = new Microsoft.Office.Interop.Excel.Application();31 Microsoft.Office.Interop.Excel.Workbook workbook = null;32 Microsoft.Office.Interop.Excel.Worksheet worksheet = null;33 workbook = repExcel.Application.Workbooks.Open(path, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);34 worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[1];35 object htmlFile = savePath + wordFileName + ".html";36 object ofmt = Microsoft.Office.Interop.Excel.XlFileFormat.xlHtml;37 workbook.SaveAs(htmlFile, ofmt, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);38 object osave = false;39 workbook.Close(osave, Type.Missing, Type.Missing);40 repExcel.Quit();41 }42 /// <summary>43 /// ppt转换为html44 /// </summary>45 /// <param name="path">要转换的文档的路径</param>46 /// <param name="savePath">转换成的html的保存路径</param>47 /// <param name="wordFileName">转换后html文件的名字</param>48 public static void PPTToHtml(string path, string savePath, string wordFileName)49 {50 Microsoft.Office.Interop.PowerPoint.Application ppApp = new Microsoft.Office.Interop.PowerPoint.Application();51 string strSourceFile = path;52 string strDestinationFile = savePath + wordFileName + ".html";53 Microsoft.Office.Interop.PowerPoint.Presentation prsPres = ppApp.Presentations.Open(strSourceFile, Microsoft.Office.Core.MsoTriState.msoTrue, Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoFalse);54 prsPres.SaveAs(strDestinationFile, Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsHTML, MsoTriState.msoTrue);55 prsPres.Close();56 ppApp.Quit();57 }
c.接下来就是调用方法:WordToHtml(string path, string savePath, string wordFileName);ExcelToHtml(string path, string savePath, string wordFileName);PPTToHtml(string path, string savePath, string wordFileName)实现相应文档的转换
然后就可以看见效果了
WORD
PPT
大家看一下这样的效果确实感觉挺丑的，特别是word，excel格式都没有了，这样的效果是难以满足要求的，那接下来我们就学习第二种方案。。。。
(2).在网上搜索如何和将office文档的pdf文档转换为flash，实现在线预览，你会发现有好几种解决方案
a.使用flashpaper将需要的文档通过简单的设置转换为SWF格式的Flash,扩展阅读：http://baike.baidu.com/view/917746.htm，不过由于我的电脑室win7，而flashpaper又不支持win7，所以只好
放弃此种方案。
b.在网上发现可以使用swftools（http://www.swftools.org/谢天谢地啊，它支持win7）将pdf格式的文件转换为flash，但是不能讲office文档转换为flash，那怎么办呢，难道这种方法又不行，可是仔
细想一下如果我们能将office文档先转换为pdf文件不就解决问题了吗,突然之间隐隐约约觉得使用office软件就可实现这一功能，于是打开word看一下究竟
哈哈果然有，不过要先装一个插件 
一切准备工作结束以后我们就可以进行编码了
c.首先说一下swftools使用：在命令行中运行pdf2swf src.pdf des.swf一般能满足需求。然后就行主要的代码的编写（即将office文档转换为pdf文档）
编写Office2Pdf.cs类
1 using System; 2 using System.Data; 3 using System.Configuration; 4 using System.Web; 5 using System.Web.Security; 6 using System.Web.UI; 7 using System.Web.UI.WebControls; 8 using System.Web.UI.WebControls.WebParts; 9 using System.Web.UI.HtmlControls; 10 using Word = Microsoft.Office.Interop.Word; 11 using Excel = Microsoft.Office.Interop.Excel; 12 using PowerPoint = Microsoft.Office.Interop.PowerPoint; 13 using Microsoft.Office.Core; 14 15 /// <summary> 16 /// Office2Pdf 将Office文档转化为pdf 17 /// </summary> 18 public class Office2Pdf 19 { 20 public Office2Pdf() 21 { 22 // 23 // TODO: 在此处添加构造函数逻辑 24 // 25 } 26 /// <summary> 27 /// Word转换成pdf 28 /// </summary> 29 /// <param name="sourcePath">源文件路径</param> 30 /// <param name="targetPath">目标文件路径</param> 31 /// <returns>true=转换成功</returns> 32 public bool DOCConvertToPDF(string sourcePath, string targetPath) 33 { 34 bool result = false; 35 Word.WdExportFormat exportFormat = Word.WdExportFormat.wdExportFormatPDF; 36 object paramMissing = Type.Missing; 37 Word.ApplicationClass wordApplication = new Word.ApplicationClass(); 38 Word.Document wordDocument = null; 39 try 40 { 41 object paramSourceDocPath = sourcePath; 42 string paramExportFilePath = targetPath; 43 Word.WdExportFormat paramExportFormat = exportFormat; 44 bool paramOpenAfterExport = false; 45 Word.WdExportOptimizeFor paramExportOptimizeFor = Word.WdExportOptimizeFor.wdExportOptimizeForPrint; 46 Word.WdExportRange paramExportRange = Word.WdExportRange.wdExportAllDocument; 47 int paramStartPage = 0; 48 int paramEndPage = 0; 49 Word.WdExportItem paramExportItem = Word.WdExportItem.wdExportDocumentContent; 50 bool paramIncludeDocProps = true; 51 bool paramKeepIRM = true; 52 Word.WdExportCreateBookmarks paramCreateBookmarks = Word.WdExportCreateBookmarks.wdExportCreateWordBookmarks; 53 bool paramDocStructureTags = true; 54 bool paramBitmapMissingFonts = true; 55 bool paramUseISO19005_1 = false; 56 wordDocument = wordApplication.Documents.Open( 57 ref paramSourceDocPath, ref paramMissing, ref paramMissing, 58 ref paramMissing, ref paramMissing, ref paramMissing, 59 ref paramMissing, ref paramMissing, ref paramMissing, 60 ref paramMissing, ref paramMissing, ref paramMissing, 61 ref paramMissing, ref paramMissing, ref paramMissing, 62 ref paramMissing); 63 if (wordDocument != null) 64 wordDocument.ExportAsFixedFormat(paramExportFilePath, 65 paramExportFormat, paramOpenAfterExport, 66 paramExportOptimizeFor, paramExportRange, paramStartPage, 67 paramEndPage, paramExportItem, paramIncludeDocProps, 68 paramKeepIRM, paramCreateBookmarks, paramDocStructureTags, 69 paramBitmapMissingFonts, paramUseISO19005_1, 70 ref paramMissing); 71 result = true; 72 } 73 catch 74 { 75 result = false; 76 } 77 finally 78 { 79 if (wordDocument != null) 80 { 81 wordDocument.Close(ref paramMissing, ref paramMissing, ref paramMissing); 82 wordDocument = null; 83 } 84 if (wordApplication != null) 85 { 86 wordApplication.Quit(ref paramMissing, ref paramMissing, ref paramMissing); 87 wordApplication = null; 88 } 89 GC.Collect(); 90 GC.WaitForPendingFinalizers(); 91 GC.Collect(); 92 GC.WaitForPendingFinalizers(); 93 } 94 return result; 95 } 96 97 /// <summary> 98 /// 把Excel文件转换成PDF格式文件 99 /// </summary>100 /// <param name="sourcePath">源文件路径</param>101 /// <param name="targetPath">目标文件路径</param>102 /// <returns>true=转换成功</returns>103 public bool XLSConvertToPDF(string sourcePath, string targetPath)104 {105 bool result = false;106 Excel.XlFixedFormatType targetType = Excel.XlFixedFormatType.xlTypePDF;107 object missing = Type.Missing;108 Excel.ApplicationClass application = null;109 Excel.Workbook workBook = null;110 try111 {112 application = new Excel.ApplicationClass();113 object target = targetPath;114 object type = targetType;115 workBook = application.Workbooks.Open(sourcePath, missing, missing, missing, missing, missing,116 missing, missing, missing, missing, missing, missing, missing, missing, missing);117 workBook.ExportAsFixedFormat(targetType, target, Excel.XlFixedFormatQuality.xlQualityStandard, true, false, missing, missing, missing, missing);118 result = true;119 }120 catch121 {122 result = false;123 }124 finally125 {126 if (workBook != null)127 {128 workBook.Close(true, missing, missing);129 workBook = null;130 }131 if (application != null)132 {133 application.Quit();134 application = null;135 }136 GC.Collect();137 GC.WaitForPendingFinalizers();138 GC.Collect();139 GC.WaitForPendingFinalizers();140 }141 return result;142 }143 ///<summary> 144 /// 把PowerPoint文件转换成PDF格式文件 145 ///</summary> 146 ///<param name="sourcePath">源文件路径</param> 147 ///<param name="targetPath">目标文件路径</param> 148 ///<returns>true=转换成功</returns> 149 public bool PPTConvertToPDF(string sourcePath, string targetPath)150 {151 bool result;152 PowerPoint.PpSaveAsFileType targetFileType = PowerPoint.PpSaveAsFileType.ppSaveAsPDF;153 object missing = Type.Missing;154 PowerPoint.ApplicationClass application = null;155 PowerPoint.Presentation persentation = null;156 try157 {158 application = new PowerPoint.ApplicationClass();159 persentation = application.Presentations.Open(sourcePath, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoFalse); persentation.SaveAs(targetPath, targetFileType, Microsoft.Office.Core.MsoTriState.msoTrue);160 result = true;161 }162 catch163 {164 result = false;165 }166 finally167 {168 if (persentation != null)169 {170 persentation.Close();171 persentation = null;172 }173 if (application != null)174 {175 application.Quit();176 application = null;177 }178 GC.Collect();179 GC.WaitForPendingFinalizers();180 GC.Collect();181 GC.WaitForPendingFinalizers();182 }183 return result;184 }185 }
然后编写Pdf2Swf.cs类调用命令行将pdf转换为swf格式的flash
1 using System; 2 using System.Data; 3 using System.Configuration; 4 using System.Web; 5 using System.Web.Security; 6 using System.Web.UI; 7 using System.Web.UI.WebControls; 8 using System.Web.UI.WebControls.WebParts; 9 using System.Web.UI.HtmlControls;10 using System.Diagnostics;11 using System.IO;12 13 /// <summary>14 /// Pdf2Swf 将pdf转化为swf15 /// </summary>16 public class Pdf2Swf17 {18 public Pdf2Swf()19 {20 //21 // TODO: 在此处添加构造函数逻辑22 //23 }24 public void PDFConvertToSWF(string sourcePath, string targetPath)25 {26 Process p = new Process();27 p.StartInfo.FileName = "cmd.exe ";28 p.StartInfo.UseShellExecute = false;29 p.StartInfo.RedirectStandardInput = true;30 p.StartInfo.RedirectStandardOutput = true;31 p.StartInfo.RedirectStandardError = true;32 p.StartInfo.CreateNoWindow = true;33 p.Start();34 string cmd = "pdf2swf.exe" + " " + sourcePath + " -o " + targetPath;35 p.StandardInput.WriteLine(cmd);36 p.Close();37 }38 }
然后只需要调用这两个类就可以实现将office转换为pdf再转换为flash的功能了
（3）最后就是实现flash的显示：这时我们还要借助工具来实现功能，那就是flexpaper,首先在网上下载所需要的flash文件、javascript文件，然后编写html代码：
View Code

效果就这样：
还不错吧，上面的工具栏也可以实现各种功能
至此为止，所有工作全部结束，大家只需要将这些代码进行整合，配合数据库使用，编写管理后台，就可以实现百度文库的效果，甚至可以投入实际使用。
欢迎大家阅读留言，望批评指正，谢谢！！
