                case 120:
                    returntext = "系统升级";
                    break;
                default:
                    returntext = "访问失败";
                    break;
            }
            return returntext;

        }
    }
}

简单使用演示（记得引入using DUANXIN）

                    SendSmsBase SmsClass = new SendSmsBase();
                    SmsClass = SendSmsFactory.CreateFactory("DXTSMSsend");
                    string content = "您的手机号：" + model.Phone + "，注册验证码：" + code + "，一天内提交有效，如不是本人操作请忽略！";
                    returncode=SmsClass.SendSmsInfo(model.Phone, content);
                    if (returncode == "账户余额不足")
                    {

                       SmsClass = SendSmsFactory.CreateFactory("WJSendSms");
                        SmsClass.SendSmsInfo(model.Phone, content);
                    }

注意有些短信平台有模板限制，

也可自己继续添加短信接口以实现暂时的免费发送。
