Serileştirme, Serialization, C#

Temel olarak serileştirme aşağıdaki kod ile anlaşılabilir ancak birazcık daha detaylı bilgi için biraz daha aşağıdaki kod yardımcı olacaktır.

             * Binary Serialization
             * Serialization can be defined as the process of storing the state of an object to a storage medium. 
             * During this process, 
             *   the public and private fields of the object 
             *   and the name of the class, 
             *   including the assembly containing the class, 
             * are converted to a stream of bytes, which is then written to a data stream. 
             * When the object is subsequently deserialized, an exact clone of the original object is created.
             * When implementing a serialization mechanism in an object-oriented environment, you have to make a number of tradeoffs between ease of use and flexibility. 
             * The process can be automated to a large extent, provided you are given sufficient control over the process.

             * or the parameters and return values of methods, 
             * into an XML stream that conforms to a specific XML Schema definition language (XSD) document. 
             * XML serialization results in strongly typed classes with public properties and fields that are converted to a serial format (in this case, XML) for storage or transport.
