使用NewtonSoft.JSON.dll来序列化和反序列化对象

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!',1,true,{property:'value'}]

这里会打印出:  ['JSON!',1,true,{property:'value'}] .
