C#版发布和订阅阿里云消息（Mqtt 物联网接入）

C# 阿里云物联网套件 MQTT 与 客户端设备相互通信示例源码

修改这三项为你的设备数据后 即可使用

        private static string productKey = "pk";
        private static string deviceName = "deviceName";
        private static string deviceSecret = "设备secret";

另外，本示例接入的是 iot-as-mqtt.cn-shanghai.aliyuncs.com，如果是其他地区的服务器，请酌情修改即可
