在.NET中使用Newtonsoft.Json转换,读取,写入

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

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":newDate(1230422400000),

//"Price":3.99,

//"Sizes":[

//"Small",

//"Medium",

//"Large"

//]

//}

Product
deserializedProduct=(Product
)JavaScriptConvert
.DeserializeObject(output,typeof
(Product
));

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))

}

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'}]
