本文实例讲述了asp.net实现word文档在线预览功能的方法。分享给大家供大家参考。具体实现方法如下：
实现方式：office文档转html，再在浏览器里面在线浏览
1、首先引入com组件中office库，然后在程序集扩展中引入word的dll
2、将Microsoft.Office.Interop.Word的嵌入互操作类型设置为 false，如图
3、主要代码：
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Microsoft.Office.Core;
using Word = Microsoft.Office.Interop.Word;
namespace Wolfy.OfficePreview
{
public class Office2HtmlHelper
{
/// <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html的保存路径</param>
/// <param name="wordFileName">转换成html的文件名字</param>
public static void Word2Html(string path, string savePath, string wordFileName)
{
Word.ApplicationClass word = new Word.ApplicationClass();
Type wordType = word.GetType();
Word.Documents docs = word.Documents;
Type docsType = docs.GetType();
Word.Document doc = (Word.Document)docsType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] { (object)path, true, true });
Type docType = doc.GetType();
string strSaveFileName = savePath + wordFileName + ".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);
wordType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod, null, word, null);
}
}
