What is XML Serialization and Binary Serialization?

Answer
XML Serialization makes it possible to convert any common language runtime objects into XML documents or streams and vise versa.

The XML Serialization enables it to convert XML documents into such a meaningful format that the programming languages can process the converted documents with ease.

Binary serialization converts the files to a binay format. In this case all the data get converted into a binary format which is not a human readable format. In binary serialization entire object state is saved, instance identity is preserved and it graphs with multiple references can be handled in this.

XML serialization doesnt allow these things.

What is XML Serialization and Binary Serialization?

XML serialization is all about serializing an object into an XML file. Being an XML file is a flat text file, the file can be viewed, shared by another application. It is a stream of characters.

XML serialization is called shallow serialization because it can serialize only public objects.

Binary serialization is all about serializing an object into a Binary file. Being a binary file is a compact file and cannot be seen like a text file. In binary serialization, image objects can also be serialized. It is a stream of bytes.

Binary serialization is called Deep serialization because it can serialize the object containing references to the other objects.

In Binary serialization the entire object state is saved where as in XML serialization only some of the object data is saved.
