阿里大鱼还未提供 .net core 版SDK，但提供了相关API，下面是.net core版实现，只是简单发送短信功能：

发送短信时：
var parms = new Dictionary<string, string>();
parms.Add(Constants.EXTEND, "123456");
parms.Add(Constants.REC_NUM, "138********");
parms.Add(Constants.SMS_FREE_SIGN_NAME, "阿里大鱼");
parms.Add(Constants.SMS_PARAM, "{\"code\":\"1234\",\"product\":\"阿里大鱼\"}");
parms.Add(Constants.SMS_TEMPLATE_CODE, "SMS_10000000");
var req = SmsHelper.SendSms("http://gw.api.taobao.com/router/rest", "appKey", "appSecret", DateTime.Now, parms);
