DataContractJsonSerializer 用法

[DataContract]
public class JsonData
{
    [DataMember(Name = "ID", Order = 0)]
    public int Id { get; set; }
[DataMember(Order = 1)]
public string Name { get; set; }

[DataMember(Order = 2)]
public DateTime Today { get; set; }

[DataMember(Order=3)]
public bool IsBool { get; set; }

[IgnoreDataMember()]
public string UnlessField { get; set; }

}

// 淮備序列化的類別資料
JsonData d1 = new JsonData()
{
    Id = 1,
    Name = "data",
    Today = DateTime.Now,
    IsBool = true,
    UnlessField = "沒用到的欄位"
};
// 初始化DataContractJsonSerializer類別
DataContractJsonSerializer dcjs = new DataContractJsonSerializer(typeof(JsonData));
string jsonString = string.Empty;

// 序列化資料
using (MemoryStream ms = new MemoryStream())
{
    dcjs.WriteObject(ms, d1);
    jsonString = Encoding.UTF8.GetString(ms.ToArray());
    Console.WriteLine(jsonString);
}

// 反序列化資料
using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString)))
{
    JsonData d2 = dcjs.ReadObject(ms) as JsonData;
    Console.WriteLine(
        "Id:{0}, Name:{1}, Today:{2}, IsBool:{3}, UnlessField:{4}",
        d2.Id,
        d2.Name,
        d2.Today,
        d2.IsBool,
        d2.UnlessField);
}
