Serializable identifies serializable classes

The class marked by [serializable] is a serializable class. Let's see what serialization means.

Serialization refers to the process of storing the status of the object instance to the storage media. In this process, first convert the Public and Private fields of the object and the name of the class (including the Assembly where the class is located) to the byte stream, and then write the byte stream into the data stream. When the object is deserialized, a copy identical to the original object will be created.

The Common Language Runtime (CLR) manages the distribution of objects in the memory. the. NET Framework uses reflection to provide an automatic serialization mechanism. After the object is serialized, the class name, assembly, and all data members of the class instance are written to the storage media. Objects usually use member variables to store references to other instances. After the class is serialized, the serialization engine tracks all serialized reference objects to ensure that the same object is not serialized multiple times .. The serialization architecture provided by the. NET Framework can automatically and correctly process object charts and circular references. The only requirement for object charts is that all objects referenced by objects being serialized must be marked as serializable (see Basic serialization ). Otherwise, an exception occurs when the serialization program attempts to serialize unlabeled objects.

When deserializing A serialized class, the class is re-created and the values of all data members are automatically restored.
