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}
