在.NET中使用Newtonsoft.Json转换,读取,写入

using Newtonsoft.Json;
Newtonsoft.Json.Converters;

//把Json字符串反序列化为对象
目标对象= JavaScriptConvert.DeserializeObject(JSON字符串,typeof (目标对象));
//把目标对象序列化为Json字符串

string Json字符串 = JavaScriptConvert.SerializeObject(目标对象);

1 .引用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	PropertyName	property
value
EndObject	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'}]
