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",

Product deserializedProduct = JsonConvert.DeserializeObject<Product>(json);

List<Product> deserializedProduct = JsonConvert.DeserializeObject<List<Product> >(json);
 

LINQ to JSON Example

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
