在.NET中使用Newtonsoft.Json转换,读取,写入

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

Productproduct=newProduct();

product.Name="Apple";

product.Expiry=newDateTime(2008,12,28);

product.Price=3.99M;

product.Sizes=newstring[]{"Small","Medium","Large"};

stringoutput=JavaScriptConvert.SerializeObject(product);

//{

//"Name":"Apple",

//"Expiry":newDate(1230422400000),

//"Price":3.99,

//"Sizes":[

//   "Small",

//   "Medium",

//   "Large"

//]

//}

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

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

JsonReaderreader=newJsonReader(newStringReader(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

StringWritersw=newStringWriter();

JsonWriterwriter=newJsonWriter(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();

stringjsonText=sw.GetStringBuilder().ToString();

Console.WriteLine(jsonText);

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