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：

复制代码 代码如下: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：

复制代码 代码如下: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。
