类似百度文库在线预览文档flash版（支持word、excel、ppt、pdf）

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的保淳?/param> 
		     /// <param name="wordFileName">转换后html文件的名譸aram> 
		     private static void WordToHtml(string path,string savePath,string wordFileName)  
		     {  
		       Word.ApplicationClass word = new Word.ApplicationClass();  
		         Type wordwordType = word.GetType();  
		         Word.Documents docs = word.Documents;  
		         Type docsdocsType = docs.GetType();  
		         Word.Document doc = (Word.Document)docsType.InvokeMember("Open",System.Reflection.BindingFlags.InvokeMethod,null,docs,new Object[] {(object)path,true,true });  
		      Type docdocType = 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的保淳?/param> 
		 　　/// <param name="wordFileName">转换后html文件的名譸aram> 
		     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[  
		         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的保淳?/param> 
		 　　/// <param name="wordFileName">转换后html文件的名譸aram> 
		     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 wordFileName);ExcelToHtml(string path,string wordFileName);PPTToHtml(string path,string wordFileName)

实现相应文档的转换

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

然后编写Pdf2Swf.cs类调用命令行将pdf转换为swf格式的flash然后编写Pdf2Swf.cs类调用命令行将pdf转换为swf格式的flash

 using System.Web.UI.HtmlControls;

 /// <summary>

     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：

             swfobject.createCSS("#flashContent","display:block;text-align:left;");

效果就这样：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。
