一切福田，不離方寸，從心而覓，感無不通。

Newtonsoft.Json序列化和反序列

下载:Newtonsoft.Json.dll

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:

1
Product product = new Product();

1
 

1
product.Name = "Apple";

1
product.Expiry = new DateTime(2008, 12, 28);

1
product.Price = 3.99M;

1
product.Sizes = new string[] { "Small", "Medium", "Large" };

1
 

1
string output = javascriptConvert.SerializeObject(product);

1
//{

1
//  "Name": "Apple",

1
//  "Expiry": new Date(1230422400000),

1
//  "Price": 3.99,

1
//  "Sizes": [

1
//    "Small",

1
//    "Medium",

1
//    "Large"

1
//  ]

1
//}

1
 

1
Product deserializedProduct = (Product)javascriptConvert.DeserializeObject(output, typeof(Product));

读取JSON

1
string jsonText = "['JSON!',1,true,{property:'value'}]";

1
 

1
JsonReader reader = new JsonReader(new StringReader(jsonText));

1
 

1
Console.WriteLine("TokenType\t\tValueType\t\tValue");

1
 

1
while (reader.Read())

1
{

1
    Console.WriteLine(reader.TokenType + "\t\t" + WriteValue(reader.ValueType) + "\t\t" + WriteValue(reader.Value))

1
}

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

1
StringWriter sw = new StringWriter();

1
JsonWriter writer = new JsonWriter(sw);

1
 

1
writer.WriteStartArray();

1
writer.WriteValue("JSON!");

1
writer.WriteValue(1);

1
writer.WriteValue(true);

1
writer.WriteStartObject();

1
writer.WritePropertyName("property");

1
writer.WriteValue("value");

1
writer.WriteEndObject();

1
writer.WriteEndArray();

1
 

1
writer.Flush();

1
 

1
string jsonText = sw.GetStringBuilder().ToString();

1
 

1
Console.WriteLine(jsonText);

1
// ['JSON!',1,true,{property:'value'}]

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