Serialization and deserialization

Serialization is the process of converting an object into a stream of data so that it can be easily transmittable over the network

Serialization

Serialization is the process of converting an object into a stream of data so that it can be easily transmittable over the network

if you want to store an object (or multiple objects) in a file for later retrieval,
you store the output of serialization. The next time you want to read the objects, you
call the deserialization methods

To serialize an object

* Create an object Stream
* Create a BinaryFormatter
* Call the BinaryFormatter.Serialize method to serialize


string data = "This must be stored in a file or folder";
FileStream fs = new FileStream("Serialization.Data", FileMode.Create);
BinaryFormatter bf = new BinaryFormatter();
bf.Serialize(fs, data);
fs.Close();

If you open the file in a notepad you can notice the contents of your file surrounded by binary numbers

DeSerialiazation

Deserialization is the process of converting a previously serialized sequence of bytes into an object

To deserialize

* Create an object Stream to read a serialized output
* Create a BinaryFormatter object
* Create an object to store a Deserialized data
* USE the BinaryFormatter.Deserialize method to deserialize the object


filestream fs = new FileStream("Serialize.Data", FileMode.Open);
BinaryFormatter bf = new BinaryFormatter();
string data = "";
data = (string)bf.Deserialize(fs);

[Serializable] public class myTestClass { public string myString = "Hello World"; public int myInt = 1234; public string[] myArray = new string[4]; private int myPrivateInt = 4321; public string myMethod() { return "Hello World"; } } class Program { static void Main() { // create new object and populate test data myTestClass test = new myTestClass(); test.myArray[0] = "qwerty"; test.myArray[1] = "asdfgh"; test.myArray[2] = "zxcvbn"; test.myArray[3] = "123456"; // these lines do the actual serialization XmlSerializer mySerializer = new XmlSerializer(typeof(myTestClass)); StreamWriter myWriter = new StreamWriter("c:/myTestClass.xml"); //serialize method which takes stream writter and class object to be serialized mySerializer.Serialize(myWriter, test); myWriter.Close(); } } //Deserialization static void Main() { myTestClass test; XmlSerializer mySerializer = new XmlSerializer(typeof(myTestClass)); FileStream myFileStream = new FileStream("c:/mtTestClass.xml",FileMode.Open); test = (myTestClass)mySerializer.Deserialize(myFileStream); }
