WORD另存为HTML

文档管理系统需要实现WORD能在线预览功能，以前觉得挺难的，经过一番研究发现，WORD自带的另存为可以保存为HTMl文件。于是考虑在每个文件上传时为其生存一份HTMl文件，这样就能实现在线预览功能。主要代码如下

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using Word = Microsoft.Office.Interop.Word;
public partial class test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

WordToHtml("d://yijian.doc");
}
/// <summary>
/// word转成html
/// </summary>
/// <param name="wordFileName"></param>
private string WordToHtml(object wordFileName)
{

//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();
Word.Document doc = (Word.Document)docsType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] { wordFileName, true, true });

//转换格式，另存为
Type docType = doc.GetType();

string wordSaveFileName = wordFileName.ToString();

string strSaveFileName = wordSaveFileName.Substring(0, wordSaveFileName.Length - 3) + "html";

object saveFileName = (object)strSaveFileName;

docType.InvokeMember("SaveAs", System.Reflection.BindingFlags.InvokeMethod, null, doc, new object[] { saveFileName, Word.WdSaveFormat.wdFormatFilteredHTML });

docType.InvokeMember("Close", System.Reflection.BindingFlags.InvokeMethod, null, doc, null);

//退出 Word
wordType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod, null, word, null);

return saveFileName.ToString();
}

}
