Windows Phone开发经验谈(5)-Json的序列化和反序列化

 

   wp7默认是支持序列化的..但是在这里给大家推荐一个类库Newtonsoft.Json，现在叫Json.net 下载地址：http://json.codeplex.com/releases/view/87440

    序列化的例子：

Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[] { "Small", "Medium", "Large" };
 string json = JsonConvert.SerializeObject(product);//{//  "Name": "Apple",//  "Expiry": new Date(1230422400000),//  "Price": 3.99,//  "Sizes": [//    "Small",//    "Medium",//    "Large"//  ]//} Product deserializedProduct = JsonConvert.DeserializeObject<Product>(json);

 

 

 Linq to json的例子

 

string json = @"{  ""Name"": ""Apple"",  ""Expiry"": new Date(1230422400000),  ""Price"": 3.99,  ""Sizes"": [    ""Small"",    ""Medium"",    ""Large""  ]}"; 
JObject o = JObject.Parse(json);

 string name = (string)o["Name"];// Apple
 JArray sizes = (JArray)o["Sizes"];
 string smallest = (string)sizes[0];// Small
