使用NewtonSoft.JSON.dll来序列化和发序列化对象

前端之家收集整理的这篇文章主要介绍了使用NewtonSoft.JSON.dll来序列化和发序列化对象前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
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'}].
