title: Convert json byte Array image to c# list
body: <p>JSON string:  </p>
  
  <pre><code> { "Result": 
             [
                  { "food_photo":255,216,255,224,0,16,74,70,73,70,0,1.....4,255,217],
                    "qty":"12",
                    "time":"23",
                    "cost":null
                  }
             ]
     }
  </code></pre>
  
  <p>My question: how to convert <code>food_photo</code> into a list?</p>
  
  <p>FYI: I use <code>public byte[] food_photo</code> in my class but it shows null when I execute my list.</p>
