C# and .NET interview questions:- How to achieve serialization and deserialization?

This is one of the most typical interview questions, which are asked in almost all of the interviews and is the favorable question of the interviewers.

Serialization: -“Serialization” is a process of converting an object
into a stream of bytes.

Deserialization: – “Deserialization” is reverse of “serialization”, where stream of bytes are converted back in to an object.

Let’s see a simple example how exactly we can do “serialization” and

It’s very simple four steps procedure as follows.

Step1: – create a new “window application” like below diagram.

Step2: – Now create a customer class in “Form1.cs” file.


Step3: – Now, we will see how exactly “serialization” is done.

Import the following namespace 
using System.IO;

privatevoidSerialize_Click(object sender, EventArgs e)
Customerobj = newCustomer();// created instance of the customer class
obj.CustomerCode = textBox1.Text;
obj.CustomerName = textBox2.Text;
IFormatter formatter = newBinaryFormatter();
Streamstream = newFileStream("E:\\Customer.bin", FileMode.Create, FileAccess.Write, FileShare.None);
formatter.Serialize(stream, obj);
textBox1.Text = "";
textBox2.Text = "";

Step4: – Similarly, we will do for “deserialization”.

privatevoidDeserialize_Click(object sender, EventArgs e)
IFormatter formatter = newBinaryFormatter();
Streamstream = newFileStream("E:\\Customer.bin", FileMode.Open, FileAccess.Read, FileShare.Read);
Customerobj = (Customer)formatter.Deserialize(stream);
textBox1.Text = obj.CustomerCode;
textBox2.Text = obj.CustomerName;

Once you have completed all the above steps now you can run your application and see the respective result.
