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}
