方法一：引入System.Web.Script.Serialization命名空間使用 JavaScriptSerializer類實現簡單的序列化序列化類：Personnel
代碼如下:
    public class Personnel
        {
            public int Id { get; set; }
            public string Name { get; set; }
        }

執行序列化反序列化：
代碼如下:
protected void Page_Load(object sender, EventArgs e)
        {
            Personnel personnel = new Personnel();
            personnel.Id = 1;
            personnel.Name = "小白";

            JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();
            //執行序列化
            string r1 = jsonSerializer.Serialize(personnel);

            //執行反序列化
            Personnel _Personnel = jsonSerializer.Deserialize<Personnel>(r1);
         }

r1輸出結果：{"Id":1,"Name":"小白"}
可以使用 ScriptIgnore屬性標記不序列化公共屬性或公共字段。
代碼如下:
        public class Personnel
        {
            [ScriptIgnore]
            public int Id { get; set; }
            public string Name { get; set; }
        }

r1輸出結果：{"Name":"小白"}

方法二：引入 System.Runtime.Serialization.Json命名空間使用 DataContractJsonSerializer類實現序列化

序列化類：People
代碼如下:
        public class People
        {
            public int Id { get; set; }
            public string Name { get; set; }
        }

執行序列化反序列化
代碼如下:
protected void Page_Load(object sender, EventArgs e)
        {
            People people = new People();
            people.Id = 1;
