Serializing and Deserializing JSON with JsonConvert

Copy

Product product = new Product();

product.Name = "Apple";

product.ExpiryDate = new DateTime(, , );

product.Price = 3.99M;

product.Sizes = new string[] { "Small", "Medium", "Large" };

string output = JsonConvert.SerializeObject(product);

//{

//  "Name": "Apple",

//  "ExpiryDate": "2008-12-28T00:00:00",

//  "Price": 3.99,

//  "Sizes": [

//    "Small",

//    "Medium",

//    "Large"

//  ]

//}

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

为了更好地控制对象的序列化方式，可以直接使用JsonSerializer。JsonSerializer能够通过JsonTextReader 和JsonTextWriter直接读取和写入JSON文本到流。也可以使用其他类型的JsonWriters，例如 JTokenReader / JTokenWriter，将对象转换为LINQ转换为JSON对象，或 转换为BsonReader / BsonWriter，以转换为BSON和从BSON转换。

Serializing JSON to a Stream with JsonSerializer

Product product = new Product();

product.ExpiryDate = new DateTime(, , );

JsonSerializer serializer = new JsonSerializer();

serializer.Converters.Add(new JavaScriptDateTimeConverter());

serializer.NullValueHandling = NullValueHandling.Ignore;

using (StreamWriter sw = new StreamWriter(@"c:\json.txt"))

using (JsonWriter writer = new JsonTextWriter(sw))

{

    serializer.Serialize(writer, product);

    // {"ExpiryDate":new Date(1230375600000),"Price":0}

}
