如何将json图像（byet数组）反序列化为asp.net中的图像？

我的json数组：

{" lstFooddtlResult":[{"class_name":"Veg","food_name":"pizza","food_photo":[255,216,255,224,0,16,74,70,73,70,0,1........],"food":"12","qty_uom":"Pcs","unit":null}]} 

C＃类：

 public class Food{ public string class_name { get; set; } public string food_name { get; set; } public photo[] photo { get; set; } public int food { get; set; } public string qty_uom { get; set; } public string unitcost { get; set; } } public class photo{ public byte food_photo { get; set; } } public class FooddtlResult{ public Food[] lstFooddtlResult { get; set; } } 

我的问题是：

1. 我的c＃类是正确的吗？

2. 如何在c＃asp.net中将字节数组转换为图像？
