序列化與還原序列化

解釋:

序列化,就是將一個對象儲存到檔案中去,而還原序列化就是將該檔案重新儲存為一個對象.

序列化的三種方式:

1.BinaryFormatter

    class BinarySerialize : ISerialize    {        FileStream fs;        string filepath = @"D:/1/1.txt";        public void Serialize(Book book)        {            using (fs = new FileStream(filepath, FileMode.Create))            {                BinaryFormatter formate = new BinaryFormatter();                formate.Serialize(fs, book);            }        }        public Book DeSerialize()        {            Book book;            using (fs = new FileStream(filepath, FileMode.Open))            {                BinaryFormatter formate = new BinaryFormatter();                book = (Book)formate.Deserialize(fs);            }            return book;        }    }

序列化之後結果如下:

2.SoapFormatter

    class SoapSerialize : ISerialize    {        FileStream fs;        string filepath = @"D:/1/2.txt";        public void Serialize(Book book)        {            using (fs = new FileStream(filepath, FileMode.Create))            {                SoapFormatter formate = new SoapFormatter();                formate.Serialize(fs, book);            }        }        public Book DeSerialize()        {            Book book;            using (fs = new FileStream(filepath, FileMode.Open))            {                SoapFormatter formate = new SoapFormatter();                book = (Book)formate.Deserialize(fs);            }            return book;        }    }

序列化之後,結果如下;

3.XmlSerializer

    class XMLSeria : ISerialize    {        FileStream fs;        string filepath = @"D:/1/3.txt";        public void Serialize(Book book)        {            using (fs = new FileStream(filepath, FileMode.Create))            {                XmlSerializer formate = new XmlSerializer(typeof(Book));                formate.Serialize(fs, book);            }        }        public Book DeSerialize()        {            Book book;            using (fs = new FileStream(filepath, FileMode.Open))            {                XmlSerializer formate = new XmlSerializer(typeof(Book));                book = (Book)formate.Deserialize(fs);            }            return book;        }    }

序列化之後,結果如下:
