C#序列化与反序列化

序列化与反序列化

解释:

序列化,就是将一个对象保存到文件中去,而反序列化就是将该文件重新保存为一个对象.

序列化的三种方式:

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;
        }
    }

序列化之后结果如下:

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;
        }

    }

序列化之后,结果如下;

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;
        }

    }

序列化之后,结果如下:
