C# interview question :- What is Serialization in .NET ?

This is a solid explanation! I remember getting this question and fumbling a bit, but your breakdown makes it really clear. It's especially useful for understanding how data persistence works behind the scenes, almost like the way ragdoll archers in games react to physics – seemingly simple, but with complex mechanics.

This is a great question! Serialization in .NET is essentially the process of converting an object into a stream of bytes so it can be stored or transmitted, and then reconstructed later.

Answer:

Serialization is a process by which we can save the state of the object by converting the object in to stream of bytes.These bytes can then be stored in database, files, memory etc.

Below is a simple code of serializing the object.

MyObject objObject = new MyObject();

objObject.Value = 100; 
// Serialization using SoapFormatter

SoapFormatter formatter = new SoapFormatter();

Stream objFileStream = new FileStream("c:\\MyFile.xml", FileMode.Create, 
FileAccess.Write, FileShare.None);

formatter.Serialize(objFileStream, objObject);

objFileStream.Close();

Below is simple code which shows how to deserialize an object.
 

//De-Serialization

Stream objNewFileStream = new FileStream("c:\\MyFile.xml", FileMode.Open, 
FileAccess.Read, FileShare.Read);

MyObject objObject =(MyObject)formatter.Deserialize(objNewFileStream);

objNewFileStream.Close();
