JSON序列化与反序列化

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
        publicclass Personnel
         {
            publicint Id { get; set; }
            publicstring Name { get; set; }
         }
执行序列化反序列化:
代码
        protectedvoid Page_Load(object sender, EventArgs e)
         {
             Personnel personnel = new Personnel();
             personnel.Id = 1;
             personnel.Name = "小白";


             JavaScriptSerializerjsonSerializer = 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。
        publicclass Personnel
         {
             [ScriptIgnore]
            publicint Id { get; set; }
            publicstring 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
        publicclass People
         {
            publicint Id { get; set; }
            publicstring Name { get; set; }
         }
执行序列化反序列化 www.zzzyk.com
代码
        protectedvoid Page_Load(object sender, EventArgs e)
         {
             People people = new People();
             people.Id = 1;
             people.Name = "小白";


             DataContractJsonSerializerjson = 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 = newMemoryStream(Encoding.UTF8.GetBytes(szJson)))
             {
                DataContractJsonSerializer serializer = newDataContractJsonSerializer(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。
代码
         [DataContract]
        publicclass People
         {
             [DataMember(Name = "id")]
            publicint Id { get; set; }
             [IgnoreDataMember]
            publicstring Name { get; set; }
         }
输出结果: {"id":1}
