导读：? 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.I

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:

  
  

 /// <summary> 

   
   
 /// word转成html 

   
   
 /// </summary> 

   
   
 /// <param name="path">要转换的文档的路径</param> 

   
   
 /// <param name="savePath">转换成的html的保存路径</param> 

   
   
 /// <param name="wordFileName">转换后html文件的名字</param> 

   
    private static void WordToHtml(string path,string savePath,string wordFileName) 
   
    { 
   
    Word.ApplicationClass word = new Word.ApplicationClass(); 
   
    Type wordType = word.GetType(); 
   
    Word.Documents docs = word.Documents; 
   
    Type docsType = docs.GetType(); 
   
    Word.Document doc = (Word.Document)docsType.InvokeMember("Open",System.Reflection.BindingFlags.InvokeMethod,null,docs,new Object[] {(object)path,true,true }); 
   
    Type docType = doc.GetType(); 
   
    string strSaveFileName = savePath + wordFileName + ".html"; 
   
    object saveFileName = (object)strSaveFileName; 
   
    docType.InvokeMember("SaveAs",doc,new object[] { saveFileName,Word.WdSaveFormat.wdFormatFilteredHTML }); 
   
    docType.InvokeMember("Close",null); 
   
    wordType.InvokeMember("Quit",word,null); 
   
    } 
   
   
 /// <summary> 

   
   
 /// excel 转换为html 

   
   
 　　/// </summary> 

   
   
 　　/// <param name="path">要转换的文档的路径</param> 

   
   
 　　/// <param name="savePath">转换成的html的保存路径</param> 

   
   
 　　/// <param name="wordFileName">转换后html文件的名字</param> 

   
    public static void ExcelToHtml(string path,string wordFileName) 
   
    { 
   
    string str = string.Empty; 
   
    Microsoft.Office.Interop.Excel.Application repExcel = new Microsoft.Office.Interop.Excel.Application(); 
   
    Microsoft.Office.Interop.Excel.Workbook workbook = null; 
   
    Microsoft.Office.Interop.Excel.Worksheet worksheet = null; 
   
    workbook = repExcel.Application.Workbooks.Open(path,Type.Missing,Type.Missing); 
   
    worksheet = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Worksheets[1]; 
   
    object htmlFile = savePath + wordFileName + ".html"; 
   
    object ofmt = Microsoft.Office.Interop.Excel.XlFileFormat.xlHtml; 
   
    workbook.SaveAs(htmlFile,ofmt,Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,Type.Missing); 
   
    object osave = false; 
   
    workbook.Close(osave,Type.Missing); 
   
    repExcel.Quit(); 
   
    } 
   
   
 /// <summary> 

   
   
 　　/// ppt转换为html 

   
   
 　　/// </summary> 

   
   
 　　/// <param name="path">要转换的文档的路径</param> 

   
   
 　　/// <param name="savePath">转换成的html的保存路径</param> 

   
   
 　　/// <param name="wordFileName">转换后html文件的名字</param> 

   
    public static void PPTToHtml(string path,string wordFileName) 
   
    { 
   
    Microsoft.Office.Interop.PowerPoint.Application ppApp = new Microsoft.Office.Interop.PowerPoint.Application(); 
   
    string strSourceFile = path; 
   
    string strDestinationFile = savePath + wordFileName + ".html"; 
   
    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); 
   
    prsPres.SaveAs(strDestinationFile,Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsHTML,MsoTriState.msoTrue); 
   
    prsPres.Close(); 
   
    ppApp.Quit(); 
   
    }

　　c.接下来就是调用方法:WordToHtml(string path,string savePath,string wordFileName);ExcelToHtml(string path,string wordFileName);PPTToHtml(string path,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>

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 try 111 { 112 application = new Excel.ApplicationClass(); 113 object target = targetPath; 114 object type = targetType; 115 workBook = application.Workbooks.Open(sourcePath,missing,116 missing,missing); 117 workBook.ExportAsFixedFormat(targetType,target,Excel.XlFixedFormatQuality.xlQualityStandard,false,missing); 118 result = true; 119 } 120 catch 121 { 122 result = false; 123 } 124 finally 125 { 126 if (workBook != null) 127 { 128 workBook.Close(true,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 try 157 { 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 catch 163 { 164 result = false; 165 } 166 finally 167 { 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

  
  
 using System; 
   
    using System.Data; 
   
    using System.Configuration; 
   
    using System.Web; 
   
    using System.Web.Security; 
   
    using System.Web.UI; 
   
    using System.Web.UI.WebControls; 
   
    using System.Web.UI.WebControls.WebParts; 
   
    using System.Web.UI.HtmlControls; 
   
    using System.Diagnostics; 
   
    using System.IO; 
   
    
   
   
 /// <summary> 

   
   
 /// Pdf2Swf 将pdf转化为swf 

   
   
 /// </summary> 

   
    public class Pdf2Swf 
   
    { 
   
    public Pdf2Swf() 
   
    { 
   
   
 // 

   
   
 // TODO: 在此处添加构造函数逻辑 

   
   
 // 

   
    } 
   
    public void PDFConvertToSWF(string sourcePath,string targetPath) 
   
    { 
   
    Process p = new Process(); 
   
    p.StartInfo.FileName = "cmd.exe "; 
   
    p.StartInfo.UseShellExecute = false; 
   
    p.StartInfo.RedirectStandardInput = true; 
   
    p.StartInfo.RedirectStandardOutput = true; 
   
    p.StartInfo.RedirectStandardError = true; 
   
    p.StartInfo.CreateNoWindow = true; 
   
    p.Start(); 
   
    string cmd = "pdf2swf.exe" + " " + sourcePath + " -o " + targetPath; 
   
    p.StandardInput.WriteLine(cmd); 
   
    p.Close(); 
   
    } 
   
    }

　　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：

效果就这样：
