Serializing Objects In C#

In the C#, Serialization is the process of converting an object into a stream of bytes to store the object or transmit it to a memory file or database such as XML or binary format.

In the c# programming language reverse process of serialization is called deserialization. In simple words serialization in C# programming language is a process of storing the object instance to a persistent storage

C# SerializableAttribute

To serialize the object, we need to apply SerializableAttribute attribute to the type. If you don't apply SerializableAttribute attribute to the type, SerializationException exception is thrown at runtime.

C# Serialization example

using System;  
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
[Serializable]
public class Student
{
   int rollNumber;
   string fullName;
    public Student(int rollNumber, string fullName)
    {
        this.rollNumber= rollNumber;
        this.fullName= fullName;
    }
}
public class SerializeExample
{
    public static void Main(string[] args)     {         FileStream stream = new FileStream("D:\\test.txt",FileMode.OpenOrCreate);
        BinaryFormatter formatter=new BinaryFormatter();
        Student objStudent= new Student(2, "Sylvia");         formatter.Serialize(stream,objStudent);
        stream.Close();     }
}
