 private void btnTest_Click(object sender, EventArgs e)

            string content = stream.ReadToEnd();
            stream.Close();

            IHTMLDocument2 doc = GetDoc2(content);
            doc.title = "新Tile";

            StreamWriter writer = new StreamWriter("c:\\test.htm", false, System.Text.Encoding.Default);
            writer.Write(doc.body.parentElement.innerHTML);
            writer.Close();

            //MessageBox.Show();
           
            
            
        }
        public IHTMLDocument2 GetDoc2(string strHtml)
        {
            mshtml.IHTMLDocument2 doc = null;
            if (strHtml == string.Empty)
                return doc;

            doc = new mshtml.HTMLDocumentClass();
            doc.designMode = "On";
            doc.write(strHtml);
