          <!--day 2-->截取之间的内容放入一个string[]里面，我的方法public string[] htmlCrwal4(string htmlstr, string begstr, string endstr)
    {
        string temp = "";
       
        int start, stop;        // start = HTML.IndexOf("</style>", 0, HTML.Length);``
        start = htmlstr.IndexOf(begstr, 0, htmlstr.Length);        stop = htmlstr.IndexOf(endstr, 0, htmlstr.Length);
        temp = htmlstr.Substring(start, stop - start);
        Regex regex = new Regex("<[^>]*>");
        string[] ss = regex.Split(temp);
        string t = "";
        foreach (string p in ss)
            if (p.Trim().Length > 0)
                t += p + "/";
        string[] sss = t.Split('/');        return sss;    }
htmlCrwal4（htmlstring,"<!--day 1-->","<!--day 2-->"）, 但是就是不对，是什么地方错了呢，或者用正则表达式能解决也可以，请大家支招，感谢了。
