利用word.application提供的方法，可以很轻易地将word文档转化为html等其它格式，下面就是实现的全部的代码：
visual c#
wordtohtml.aspx
<%@ page language=c# codebehind=wordtohtml.aspx.cs autoeventwireup=false
inherits=aspxwebcs.wordtohtml %>
<!doctype html public -//w3c//dtd html 4.0 transitional//en >
<html>
<head>
<title>wordtohtml</title>
<meta name=generator content=microsoft visual studio .net 7.1>
<meta name=code_language content=c#>
<meta name=vs_defaultclientscript content=javascript>
<meta name=vs_targetschema content=http://schemas.microsoft.com/intellisense/ie5>
</head>
<body ms_positioning=gridlayout>
<form id=form1 method=post runat=server>
</form>
</body>
</html>

public class wordtohtml : system.web.ui.page
{
private void page_load(object sender, system.eventargs e)
{
// 在此处放置用户代码以初始化页面
word.applicationclass word = new word.applicationclass();
type wordtype = word.gettype();
word.documents docs = word.documents;
// 打开文件
type docstype = docs.gettype();
object filename = d://tmp//aaa.doc;
word.document doc = (word.document)docstype.invokemember(open,
system.reflection.bindingflags.invokemethod, null, docs, new object[] {filename, true, true});
// 转换格式，另存为
type doctype = doc.gettype();
object savefilename = d://tmp//aaa.html;
//下面是microsoft word 9 object library的写法，如果是10，可能写成：
//doctype.invokemember(saveas, system.reflection.bindingflags.invokemethod,
null, doc, new object[]{savefilename, word.wdsaveformat.wdformatfilteredhtml});
///其它格式：
///wdformathtml
///wdformatdocument
///wdformatdostext

///wdformatencodedtext
///wdformatrtf
///wdformattemplate
///wdformattext
///wdformattextlinebreaks
///wdformatunicodetext
