asp.net如何实现word文档在线预览

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

 

C# 代码   复制

using System;
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);

        }
    }
}

 

调用

Office2HtmlHelper.Word2Html(MapPath("/Doc/分析某网站的SEO策略(外链篇).doc"), MapPath("/Html/"), "分析某网站的SEO策略(外链篇)");
