C#将对象转换成JSON字符串，Newtonsoft.Json (JSON.NET)

官方API说明文档

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:

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‘}]
