word,ppt,excel转换为html

因为最近上班做邮箱附件的预览功能，上网找到的解决方案是转为html文件，自己总结了一下：

1.先添加office组建，右键网站，点击添加引用

2.选择.NET找到你需要的组件，例如Microsoft.Office.Interop.Excel(版本为12.0.0.0)，我这里用的还有ppt,word,三个都添加上

 

3.开始写代码

  1 using System;
  2 using System.Collections.Generic;
  3 using System.Linq;
  4 using System.Web;
  5 using System.Web.UI;
  6 using System.Web.UI.WebControls;
  7 using word = Microsoft.Office.Interop.Word;//引入对应的组件
  8 using System.IO;
  9 using ppt = Microsoft.Office.Interop.PowerPoint;
 10 using Microsoft.Office.Core;
 11 using Microsoft.Office.Interop;
 12 
 13 namespace Web.MailManage
 14 {
 15     public partial class WordShow : System.Web.UI.Page
 16     {
 17         protected void Page_Load(object sender, EventArgs e)
 18         {
　　　　　　　　　　string newurl = string.Empty;
                  newurl = wordtohtml(filename);//转换word文档
                  Response.Redirect(filename);//跳转到转换后的html文件，这里要注意一样要路径正确，否则没有效果，也就是看到转换的文件在什么路径
 19         }

 23         /// <summary> 
 24         /// word转成html 
 25         /// </summary> 
 26         /// <param name="wordfilename"></param> 
 27         private string wordtohtml(object wordfilename)
 28         {
 29             //在此处放置用户代码以初始化页面 
 30             word.Application word = new word.Application();
 31             Type wordtype = word.GetType();
 32             word.Documents docs = word.Documents;
 33             //打开文件 
 34             Type docstype = docs.GetType();
 35             word.Document doc = (word.Document)docstype.InvokeMember("open", System.Reflection.BindingFlags.InvokeMethod, null, docs, new object[] { wordfilename, true, true });
 36             //转换格式，另存为 
 37             Type doctype = doc.GetType();
 38             string wordsavefilename = wordfilename.ToString();
 39             string strsavefilename = wordsavefilename.Substring(0, wordsavefilename.Length - 3) + "html";
 40             object savefilename = (object)strsavefilename;
 41             doctype.InvokeMember("saveas", System.Reflection.BindingFlags.InvokeMethod, null, doc, new object[] { savefilename, Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatFilteredHTML });
 42             doctype.InvokeMember("close", System.Reflection.BindingFlags.InvokeMethod, null, doc, null);
 43             // 退出 word 
 44             wordtype.InvokeMember("quit", System.Reflection.BindingFlags.InvokeMethod, null, word, null);
 45             return savefilename.ToString();
 46         }

 51             string saveFileName = filePath + ".html";
 52             Microsoft.Office.Interop.PowerPoint.Application ppt = new Microsoft.Office.Interop.PowerPoint.Application();

 57             pp.SaveAs(saveFileName, Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsHTML, Microsoft.Office.Core.MsoTriState.msoTriStateMixed);
 58             pp.Close();
 59             //返回文件名

 94             System.Diagnostics.Process[] process = System.Diagnostics.Process.GetProcessesByName("EXCEL");//依据时间杀灭进程
 95             foreach (System.Diagnostics.Process p in process)
 96             {
 97                 if (DateTime.Now.Second - p.StartTime.Second > 0 && DateTime.Now.Second - p.StartTime.Second < 5)
 98                 {
 99                     p.Kill();
100                 }
101             }
102 
103             return savefilename.ToString();
104 
105         }
106     }
107 }

以上是转换成为html文件的方法，转换成功厚在你文件夹下会生对应的图片文件夹，和样式文件，和html文件。

转换成功后直接跳转到转换的html文件，这样office的预览就成功了
