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}
