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:

前台调用:

    <asp:Button ID="BinaryFactory" runat="server" Text="BinarySerialize" οnclick="Btn_Click" /><asp:Button ID="SoapFactory" runat="server" Text="SoapSerialize" οnclick="Btn_Click" /><asp:Button ID="XMLFactory" runat="server" Text="XMLSerialize" οnclick="Btn_Click"  />protected void Btn_Click(object sender, EventArgs e){Book book = new Book();book.BookName = "入门经典";book.Price = 120;string id = ((Button)sender).ID;BaseFacotry factory = (BaseFacotry)Assembly.Load("Define").CreateInstance("Define." + id);ISerialize serialize = factory.CreateSerialize();serialize.Serialize(book);Book b = serialize.DeSerialize();Response.Write(b.ToString());}
