导读：这里下载:http://www.newtonsoft.com/products/json/ 安装: 1 . 解压下载文件,得到Newtonsoft.Json.dll 2.在项目中添加引用.. 序列化和反序列在.net项目中: Product product = new Product (); product.Name = "Apple" ; product.Expiry = new DateTime (200

这里下载:http://www.newtonsoft.com/products/json/
安装:
1.解压下载文件,得到Newtonsoft.Json.dll
2.在项目中添加引用..
序列化和反序列在.net项目中:

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 output = javascriptConvert.SerializeObject(product);

//{

// "Name": "Apple",

// "Expiry": new Date(1230422400000),

// "Price": 3.99,

// "Sizes": [

// "Small",

// "Medium",

// "Large"

// ]

//}

Product deserializedProduct = (Product)javascriptConvert.DeserializeObject(output,typeof(Product));

读取JSON

string jsonText = "['JSON!',1,true,{property:'value'}]";

JsonReader reader = new JsonReader(new StringReader(jsonText));

Console.WriteLine("TokenTypettValueTypettValue");

while (reader.Read())

 Console.WriteLine(reader.TokenType + "tt" + WriteValue(reader.ValueType) + "tt" + WriteValue(reader.Value))

结果显示:

TokenType

ValueType

Value

StartArray

null

String

System.String

JSON!

Integer

System.Int32

Boolean

System.Boolean

True

StartObject

null

PropertyName

System.String

property

String

System.String

value

EndObject

null

EndArray

null

JSON写入

StringWriter sw = new StringWriter();

JsonWriter writer = new JsonWriter(sw);

writer.WriteStartArray();

writer.WriteValue("JSON!");

writer.WriteValue(1);

writer.WriteValue(true);

writer.WriteStartObject();

writer.WritePropertyName("property");

writer.WriteValue("value");

writer.WriteEndObject();

writer.WriteEndArray();

writer.Flush();

string jsonText = sw.GetStringBuilder().ToString();

Console.WriteLine(jsonText);

// ['JSON!',{property:'value'}]

这里会打印出: ['JSON!',{property:'value'}].
