最近在做word文档在线阅读,找了种种方法、控件以后,回归到word转HTML,在线阅读....
1下是后台代码,前台html页面默许代码便可。
由于用文件以下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
using Word = Microsoft.Office.Interop.Word;
using Word = Microsoft.Office.Interop.Word;
没有援用好组件时,此处会报错,找不到Interop之类的,
这时候需要在援用里面援用组件.net下的Microsoft.Office.Interop.Visio,Microsoft.Office.Interop.Word
后台代码以下:
protected void Page_Load(object sender, EventArgs e)
{
string relativePath = Request.QueryString["FilePath"]; //相对路径 ,从跳转页面得到文件相对路径。
if (relativePath == "" || relativePath==null) return;
string serverPath = Server.MapPath(relativePath); //相对转
服务器对应路径
string html = serverPath.Replace(".doc", ".html");
if (!File.Exists(@html)) //html页面不存在,把word转换成html
{
string filename = WordToHtml(serverPath);
StreamReader fread = new StreamReader(filename, System.Text.Encoding.GetEncoding("gb2312"));
string ss = fread.ReadToEnd();
Response.Write(ss); //直接写字符串到网页会发现,文字可显示,图片、表格没法显示。因此在后面重跳转到html文件页面。
fread.Close();
fread.Dispose();
}
html = relativePath.Replace(".doc", ".html");
//html文件也存储在一样的路径下,
//只需要改了原路径的后缀便可得到html文件路径
Response.Redirect(html);
return;
}
/// <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.Application word = new Word.Application();
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();
}
