ASP.NET 实现word文档在线预览功能代码-Word转Html

public void OpenFile()
    {
        Microsoft.Office.Interop.Word.Application wapp = new Microsoft.Office.Interop.Word.Application();   //在office软件中打开
        wapp.Visible = true;
        object filename = "F:\\word测试.doc";
        object isread = false;
        object isvisible = true;
        object miss = System.Reflection.Missing.Value;
        wapp.Documents.Open(ref filename, ref miss, ref isread, ref miss, ref miss, ref miss, ref miss, ref miss,
                            ref miss, ref miss, ref miss, ref isvisible, ref miss, ref miss, ref miss, ref miss);
        wapp = null;
    }

还有种是保存成html文件，然后可以打开页面直接实现在线预览功能，主要代码如下：

复制代码
using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using Word = Microsoft.Office.Interop.Word;

public partial class Htmltest : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void btn_Click(object sender, EventArgs e)
    {
        WordToHtml("F:\\word测试.doc"); 
    }

    /// 

    /// 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.ApplicationClass word = new Word.ApplicationClass();
        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();
    }
}
