.net 序列化 与反序列化 Serializable

序列化：序列化指的是 将对象 通过流的方式 保存为一个文件。 反序列化则是将该文件还原成 对象的过程。

序列化的作用：序列化可以跨语言跨平台 传输数据，将某一对象序列化成通用的文件格式在进行传输。 比如XML 等。

C# 中的序列化方法有一下4种：

1.BinaryFormatter

2.SoapFormatter(.net 3.5 开始便废弃它了，不要在生产代码中使用它)

3.XmlSerializer

4.Json

首先查看 BinaryFormatter 序列化 反序列化

//Serializable 标示可序列化
    [Serializable]
    public class Cars
    {
        public ArrayList carBrandList; //品牌数组
        public Cars()
        {
            carBrandList = new ArrayList();
        }
        public string CarName;
        [NonSerialized] //标示不可序列化
      public string carNumber;

        public string CarID
        { get; set; }

        private string _carPrice;
        public void SetCarPrice(string price)
        {
            _carPrice = price;
        }
    }
        static void Main(string[] args)
        {
            //实例化对象
         Cars cars = new Cars();
            cars.CarID = "";
            cars.carBrandList.Add("宝马");
            cars.carBrandList.Add("路虎");
            cars.carBrandList.Add("布加迪");
            cars.CarName = "路虎-揽胜极光";
            cars.carNumber = "闽A-0888A";
            cars.SetCarPrice("590000.00");

            //BinaryFormatter 序列化
            string strFile = "c:\\cars.txt";
            using (FileStream fs = new FileStream(strFile, FileMode.Create))
            {
                BinaryFormatter formatter = new BinaryFormatter();
                formatter.Serialize(fs, cars);
            }
           Cars car = DeSerialize(); //
        }
         //反序列化
        public Cars DeSerialize()
        {
            string strFile = "c:\\cars.txt";
            Cars cars;
            using (FileStream fs = new FileStream(strFile, FileMode.Open))
            {
                BinaryFormatter formatter = new BinaryFormatter();
                cars = (Cars)formatter.Deserialize(fs);
            }
            return cars;
        }

接下来查看下 反序列化回来的对象属性

SoapFormatter序列化反序列化

  //Serializable 标示可序列化
    [Serializable]
    public class Cars
    {
        public ArrayList carBrandList; //品牌数组

        public Cars()
        {
            carBrandList = new ArrayList();
        }

        public string CarName;

        [NonSerialized] //标示不可序列化
        public string carNumber;

        public string CarID
        { get; set; }

        private string _carPrice;

        public void SetCarPrice(string price)
        {
            _carPrice = price;
        }

    }
static void Main(string[] args)
{
            //SoapFormatter 序列化
         string strSoapFile = "c:\\cars.Soap";
            using (FileStream fs = new FileStream(strSoapFile,     FileMode.Create))
            {
                SoapFormatter formatter = new SoapFormatter();
                formatter.Serialize(fs, cars);
            }
          Cars scar = DeSoapSerialize();
}

          //反序列化
        public Cars DeSoapSerialize()
        {
            string strFile = "c:\\cars.Soap";
            Cars cars;
            using (FileStream fs = new FileStream(strFile, FileMode.Open))
            {
                SoapFormatter formatter = new SoapFormatter();
                cars = (Cars)formatter.Deserialize(fs);
            }
            return cars;
        }

XmlSerializer 序列化 反序列化

//Serializable 标示可序列化
    [Serializable]
    public class Cars
    {
        public ArrayList carBrandList; //品牌数组

        public Cars()
        {
            carBrandList = new ArrayList();
        }

        public string CarName;

        [NonSerialized] //标示不可序列化
        public string carNumber;

        public string CarID
        { get; set; }

        private string _carPrice;

        public void SetCarPrice(string price)
        {
            _carPrice = price;
        }

    }
        static void Main(string[] args)
        {

            //实例化对象
         Cars cars = new Cars();
            cars.CarID = "";
            cars.carBrandList.Add("宝马");
            cars.carBrandList.Add("路虎");
            cars.carBrandList.Add("布加迪");
            cars.CarName = "路虎-揽胜极光";
            cars.carNumber = "闽A-0888A";
            cars.SetCarPrice("590000.00");

            //XmlSerializer 序列化
            string strXMLFile = "c:\\cars.XML";
            using (FileStream fs = new FileStream(strXMLFile, FileMode.Create))
            {
                XmlSerializer serializer = new XmlSerializer(typeof(Cars));
                serializer.Serialize(fs, cars);
            }
            Cars xcar = DeXMLSerialize();
        }

         public Cars DeXMLSerialize()
        {
            string strFile = "c:\\cars.XML";
            Cars cars;
            using (FileStream fs = new FileStream(strFile, FileMode.Open))
            {
                XmlSerializer formatter = new XmlSerializer(typeof(Cars));
                cars = (Cars)formatter.Deserialize(fs);
            }
            return cars;
        }
 

都执行完成后 大家可以查看下生产的 的 文件，查看下反序列化出来的结果 可以发现

1.单有[NonSerialized] 表示的时候  BinaryFormatter 与 Soap 是无法序列化对象属性。

2.private 私有属性 XML方式是无法序列化的。

3.XML可序列化[NonSerialized]标示的 属性。
