使用NewtonSoft.JSON.dll来序列化和发序列化对象

从这里下载: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("TokenType\t\tValueType\t\tValue");

while (reader.Read())

{

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

}

结果显示:

TokenType	ValueType	Value
StartArray	null	null
String	System.String	JSON!
Integer	system.int32	1
Boolean	System.Boolean	True
StartObject	null	null
PropertyName	System.String	property
String	System.String	value
Endobject	null	null
Endarray	null	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'}].
