c# json轉成類對象

1、引用

using System.Web.Script.Serialization;

2、定義類

class FaceCallback
    {
        public string device_id { get; set; }
        public int pass_status { get; set; }
        public string timestamp { get; set; }
        public string user_id { get; set; }
    }

3、轉換為類對象

 JavaScriptSerializer js = new JavaScriptSerializer();   //實例化一個能夠序列化數據的類
 FaceCallback faceCallback = js.Deserialize<FaceCallback>(content);//content為json格式數據
 string deviceId=faceCallback.device_id;
