方法一:引入System.Web.Script.Serialization命名空间使用 JavaScriptSerializer类实现简单的序列化
序列化类:Personnel
- public class Personnel
- {
- public int Id { get; set; }
- public string Name { get; set; }
- }
执行序列化反序列化
- 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输出结果:{"Id":1,"Name":"小白"}
可以使用 ScriptIgnore属性标记不序列化公共属性或公共字段。
- public class Personnel
- {
- [ScriptIgnore]
- public int Id { get; set; }
- public string Name { get; set; }
- }
r1输出结果:{"Name":"小白"}
方法二:引入 System.Runtime.Serialization.Json命名空间使用 DataContractJsonSerializer类实现序列化
序列化类:People
- public class People
- {
- public int Id { get; set; }
- public string Name { get; set; }
- }
执行序列化反序列化
- 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输出结果:{"Id":1,"Name":"小白"}
可以使用IgnoreDataMember:指定该成员不是数据协定的一部分且没有进行序列化,DataMember:定义序列化属性参数,使用DataMember属性标记字段必须使用DataContract标记类 否则DataMember标记不起作用。
- [DataContract]
- public class People
- {
- [DataMember(Name = "id")]
- public int Id { get; set; }
- [IgnoreDataMember]
- public string Name { get; set; }
- }
输出结果: {"id":1}
