利用Newtonsoft.Json序列化,反序列化,读取,写入

using

Newtonsoft.Json;

using

Newtonsoft.Json.Converters;

//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);

代码：

protected void Page_Load(object sender, EventArgs e)
{
Student student = new Student("kntao", 20);
student.Alias[0] = "小孔";
student.Alias[1] = "孔某某";

// 序列化
string outPut = JavaScriptConvert.SerializeObject(student);
Response.Write("序列化输出============================</br>");
Response.Write(outPut + "</br>");
// 反序列化
Student stu = (Student)JavaScriptConvert.DeserializeObject(outPut, typeof(Student));
Response.Write("反序列化输出============================</br>");
Response.Write("Name:" + stu.Name + " Alias:" +  stu.Alias[0]+"," +stu.Alias[1] + " Age:" + stu.Age + "</br>" );
// 读取JSON
string jsonText = "['JSON!',1,true,{property:'value'}]";
JsonReader reader = new JsonReader(new StringReader(jsonText));
Response.Write("JSON 读取============================</br>");
while (reader.Read())
{
Response.Write(reader.TokenType + "----" + reader.ValueType + "----" + reader.Value);
Response.Write("</br>");
}
// 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 json = sw.GetStringBuilder().ToString();
Response.Write("JSON 写入============================</br>");
Response.Write(json + "</br>");
}

运行结果：
