C#实现JSON字符串序列化与反序列化的方法

public string GetJsonString() 
{ 
 List<Product> products = new List<Product>(){ 
 new Product(){Name="苹果",Price=5}, 
 new Product(){Name="橘子",Price=5}, 
 new Product(){Name="干柿子",Price=00}

 productlistGetProducts = products; 
 return new JavaScriptSerializer()Serialize(productlist)); 
} 
 
public class Product 
{ 
 public string Name { get; set; } 
 public double Price { get; set; } 
} 
 
public class ProductList 
{ 
 public List<Product> GetProducts { get; set; } 
} 

public static List<T> JSONStringToList<T>(this string JsonStr) 
{ 
 JavaScriptSerializer Serializer = new JavaScriptSerializer(); 
 List<T> objs = SerializerDeserialize<List<T>>(JsonStr); 
 return objs; 
} 
 
public static T Deserialize<T>(string json) 
{ 
 T obj = ActivatorCreateInstance<T>(); 
 using (MemoryStream ms = new MemoryStream(EncodingUTFGetBytes(json))) 
 { 
 DataContractJsonSerializer serializer = new DataContractJsonSerializer(objGetType()); 
 return (T)serializerReadObject(ms); 
 } 
} 
 
string JsonStr = "[{Name:'苹果',Price:5},{Name:'橘子',Price:5},{Name:'柿子',Price:16}]"; 
List<Product> products = new List<Product>(); 
products = JSONStringToList<Product>(JsonStr); 
 
foreach (var item in products) 
{ 
 ResponseWrite(itemName + ":" + itemPrice + "<br />"); 
} 
 
public class Product

}
