.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。
