按照长度分割字符串

使用正则表达式分割字符串：

            string str = "5B5B5B5B0003220101935D5D5D5D5B5B5B5B0003220101935D5D5D5D";
            Regex reg = new Regex(@".{1,3}");
            MatchCollection mc = reg.Matches(str);
            foreach (Match m in mc)
            {
                Response.Write(m.ToString() + "</br>");
            }
