淺析JSON序列化與反序列化

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
復制代碼 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：
復制代碼 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。
復制代碼 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
復制代碼 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
復制代碼 代碼如下:
protected void Page_Load(object sender, EventArgs e)
        {
            People people = new People();
            people.Id = 1;
            people.Name = "小白";

            DataContractJsonSerializer json = new DataContractJsonSerializer(people.GetType());
            string szJson = "";
            //序列化
            using (MemoryStream stream = new MemoryStream())
            {
                json.WriteObject(stream, people);
                szJson = Encoding.UTF8.GetString(stream.ToArray());
            }
            //反序列化
            using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(szJson)))
            {
                DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(People));
                People _people = (People)serializer.ReadObject(ms);
            }
         }

szJson輸出結果：{"Id":1,"Name":"小白"}

可以使用IgnoreDataMember:指定該成員不是數據協定的一部分且沒有進行序列化，DataMember:定義序列化屬性參數，使用DataMember屬性標記字段必須使用DataContract標記類 否則DataMember標記不起作用。
復制代碼 代碼如下:
[DataContract]
        public class People
        {
            [DataMember(Name = "id")]
            public int Id { get; set; }
            [IgnoreDataMember]
            public string Name { get; set; }
        }

輸出結果: {"id":1}
