C#实现的json序列化和反序列化代码实例

  //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
  [Serializable]
  public class Person
  {
     
    private int id;
    /// <summary>
    /// id
    /// </summary>
    public int Id
    {
      get { return id; }
      set { id = value; }
    }

    /// <summary>
    /// 姓名
    /// </summary>
    public string Name
    {
      get { return name; }
      set { name = value; }
    }
  }
 
  //方法二：引入 System.Runtime.Serialization.Json命名空间使用 DataContractJsonSerializer类实现序列化
  //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]
