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。
