Newtonsoft.Json序列化和反序列

//把Json 字符串反序列化为对象
目标对象= JavaScriptConvert.DeserializeObject(JSON字符串,typeof (目标对象));
//把目标对象序列化为Json 字符串

string


 Json


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

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:

lJSON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'}] .
