Uses for serialization
Serialization is used in many scenarios, but the main purpose is to save the state of an object in order to have the ability to recreate the same object when required. It is an important to let the user save work and then be able to continue from that point at a later time. This is a common need in various tools and applications. Serialization is also used in creating a clone of an object.

Another important need for serialization arises when the object is required to travel electronically over wire. In such cases the objects are serialized and deserialized. In fact, serialization is one of the fundamental requirements for techniques such as .NET Remoting.

Even the hibernation mode in the Windows Operating system can be considered a form of serialization.

Types of serialization
The .NET Framework provides certain built-in mechanisms which can be used to serialize and deserialize objects. This functionality can be found in the System.Runtime.Serialization and the System.Xml.Serialization namespaces of the .NET Framework.

Serialization in .NET can be classified into four types as shown in Figure B:
