C#中用JavaScriptSerializer和Json.Net操作json格式的文件

1.json文件

2.写出对应的类

         //折扣
         public class Discount
         {
             public string Qty { get; set; }
             public string percentage { get; set; }
         }
         //产品信息
         public class ProductInfo
         {
             public string packing { get; set; }
             public string Qty { get; set; }
             public List<Discount> Discount { get; set; }
         }
         //总信息
         public class RootObject
         {
             public string id { get; set; }
             public string date { get; set; }
             public List<ProductInfo> productInfo { get; set; }
         }

3.JavaScriptSerializer操作json

             string jsonText = File.ReadAllText("JSON文件.json");
             JavaScriptSerializer jss = new JavaScriptSerializer();
             RootObject root = jss.Deserialize<RootObject>(jsonText);
             Console.WriteLine(root.id + "==========" + root.date);
             Console.WriteLine(root.productInfo[].packing + "======" + root.productInfo[].Qty);
             Console.WriteLine(root.productInfo[].Discount[].Qty + "========" + root.productInfo[].Discount[].percentage);
             Console.WriteLine(root.productInfo[].Discount[].Qty + "=======" + root.productInfo[].Discount[].percentage);
             Console.ReadKey();

3.1运行结果

4.Json.Net操作json

             string jsonText = File.ReadAllText("JSON文件.json");
             //反序列化json字符串
             RootObject root=JsonConvert.DeserializeObject<RootObject>(jsonText);
             Console.WriteLine(root.id + "==========" + root.date);
             Console.WriteLine(root.productInfo[].packing + "======" + root.productInfo[].Qty);
             Console.WriteLine(root.productInfo[].Discount[].Qty + "========" + root.productInfo[].Discount[].percentage);
             Console.WriteLine(root.productInfo[].Discount[].Qty + "=======" + root.productInfo[].Discount[].percentage);
             Console.ReadKey();

4.1运行结果

4.2使用Json.Net序列化

             Student stu=new Student();
             stu.Id = ;
             stu.Name = "卡卡西";
             stu.English = ;
             stu.Math = ;
             string jsonString=JsonConvert.SerializeObject(stu);
             Console.WriteLine(jsonString);
             Console.ReadKey();
