在线预览⽂档（⽀持word、excel、ppt、pdf）+在线预览⽂档
html版（转）
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);

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 }

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();有哪些网页设计公司
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
放弃此种⽅案。
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
