雖然阿里云短信接口，提供了很多種語(yǔ)言的SKD，但是對(duì)應(yīng)C#而言，如果使用阿里云SDK，你的項(xiàng)目中需要引入一大堆的dll，像這樣：
我只需要發(fā)個(gè)短信，沒(méi)必要引入這么多dll吧。于是，根據(jù)阿里云官方文檔，接口SDK源碼，自己整理封裝了一個(gè)類，完成發(fā)短信的操作。閑話不多說(shuō)，直接上代碼：

var random = new Random().Next(100000, 999999).ToString();
AliyunSmsHelper.SendSms("1******4902", "短信簽名", "SMS_262******", "{\"code\":\"" + random + "\"}");
