去掉所有的Html代码 直接调用StripHTML方法就行了

/// <summary>

        /// 过滤html标签

        /// </summary>

        /// <param name="strHtml">html的内容</param>

        /// <returns></returns>

            stringToStrip = Regex.Replace(stringToStrip, "

", "\n", RegexOptions.IgnoreCase | RegexOptions.Compiled);

            stringToStrip = Regex.Replace(stringToStrip, "\"", "''", RegexOptions.IgnoreCase | RegexOptions.Compiled);

            return stringToStrip;

        }
