方法一:引入System.Web.Script.Serialization命名空間使用JavaScriptSerializer類別實作簡單的序列化序列化類別:Personnel
public class Personnel { public int Id { get; set; } public string Name { get; set; } }
執行序列化反序列化:
protected void Page_Load(object sender, EventArgs e) { Personnel personnel = new Personnel(); personnel.Id = 1; personnel.Name = "小白"; JavaScriptSerializer jsonSerializer = new JavaScriptSerializer(); //执行序列化 string r1 = jsonSerializer.Serialize(personnel); //执行反序列化 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欄位。
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類別實作序列化
序列化類別:People使用DataContractJsonSerializer類別實作序列化
序列化類別:People
rerree化反序列化
public class People { public int Id { get; set; } public string Name { get; set; } }
szJson輸出結果:{"Id":1,"Name":"小白"}
可以使用IgnoreDataMember:指定該成員不是資料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屬性標記欄位必須使用DataContract標記類別否則DataMember標記不起作用。
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); } }
輸出結果: {"id":1}
