//a file stream is created
IFormatter format = new BinaryFormatter();
Stream stream1 = new FileStream(@"E:\Example.txt",FileMode.Create,FileAccess.Write);
//serialization of the object of the class check is done
format.Serialize(stream1, ob);
stream1.Close();
//a file stream is created
stream1 = new FileStream(@"E:\Example.txt",FileMode.Open,FileAccess.Read);
//the object of the class check is deserialized
Check ob1 = (Check)format.Deserialize(stream1);
//the data is written to the console
Console.WriteLine(ob1.identity);
Console.WriteLine(ob1.nam);
Console.ReadKey();
}
}
}

Output:

In the above program, a namespace called demo is defined. Then a Serializable attribute is defined. A class check is defined to demonstrate the concept of serialization using this class. Two properties identity and nam are defined in the class to which the values 10 and Shobha are assigned respectively. Then an object of the check class is created to serialize it to the file Example.txt. Then a formatter class is defined to convert the object of the class check to a binary stream.

Then a file stream object is created to open the file Example.txt in write mode to write the values of the properties identity and nam into it. Then serialize method is used to transfer the binary data into the text file. Finally, We use deserialize method to deserialize the contents of the text file Example.txt and the data is written to the console as shown in the output snapshot above.
