using System.Web.UI.WebControls;

using System.IO;

using Word = Microsoft.Office.Interop.Word;

using Word = Microsoft.Office.Interop.Word;没有引用好组件时，此处会报错，找不到Interop之类的，

这时需要在引用里面引用组件.net下的Microsoft.Office.Interop.Visio，Microsoft.Office.Interop.Word

后台代码如下：

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、表格无法显示。因此在后面重跳转到html文件页面。

fread.Close();

fread.Dispose();

html = relativePath.Replace(".doc", ".html");

//html文件也存储在同样的路径下，

//只需要改了原路径的后缀即可得到html文件路径

Response.Redirect(html);

return;

/// word转成html

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();
