URL编码方法

一、URL编码

        /// <summary>
        /// URL编码 (=、？、& 不参于编码)
        /// </summary>
        /// <param name="str"></param>
        /// <returns></returns>
        public static string HtmlUrlEncode(string str)
        {
            string result = string.Empty;

            result = System.Web.HttpUtility.UrlEncode(str);

            result = result.Replace("%3d", "=").Replace("%3f", "?").Replace("%26", "&");

            return result;
        }

二、URL解码

        /// <summary>
        /// URL解码
        /// </summary>
        /// <param name="str"></param>
        /// <returns></returns>
        public static string HtmlUrlDecode(string str)
        {
            string result = string.Empty;

            result = System.Web.HttpUtility.UrlDecode(str);

            result = result.Replace("%3d", "=").Replace("%3f", "?").Replace("%26", "&");

            return result;
        }

注：在WinForm中记得引用 System.Web 命名空间。
