研究人員發現透過OpenSSL旁路攻擊，截取裝置在電子活動中所產生的各種訊號，例如電磁輻射、功耗變化，甚至是聲音、溫度等變化，從中擷取出金鑰。

[.NET] [C#] [JSON.NET] Serialize序列化與Deserialize反序列

[.NET] [C#] [JSON.NET]
使用JSON.NET
SerializeObject()將物件與Dataset序列化(Serialize)為JSON
DeserializeObject()將Json反序列化(Deserialize)為物件

JSON

JSON是一種簡單輕量的資料交換格式。可用 陣列 [ ] 與 物件 { } 來寫入資料，資料的名稱與值;name / value 成對，名稱與值的中間以 : 隔開，如下:

[
  {
    "Name": "Jason",
    "Age": 18,
    "Gender": "male"
  },
  {
    "Name": "Wendy",
    "Age": 30,
    "Gender": "female"
  },
  {
    "Name": "Alex",
    "Age": 50,
    "Gender": "male"
  },
  {
    "Name": "Amanda",
    "Age": 21,
    "Gender": "female"
  }
]
