asp.net实现word文档在线预览功能的方法

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;
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)");

希望本文所述对大家的asp.net程序设计有所帮助。
