GetObjectDataSerializationInfo

GetObjectData is a method used in some programming languages, particularly older versions of .NET, to support serialization. When an object is being serialized, the serialization runtime invokes this method on the object to retrieve the data that needs to be saved. This data is typically stored in a SerializationInfo object.

The GetObjectData method is part of the ISerializable interface. Classes that implement this interface must provide their own implementation of GetObjectData. Within this method, developers explicitly specify which fields or properties of the object should be serialized by adding them to the SerializationInfo object using methods like AddValue. This gives fine-grained control over the serialization process.

When an object implementing ISerializable is deserialized, the serialization runtime uses the information stored in SerializationInfo to reconstruct the object. This mechanism allows for custom serialization logic, enabling developers to handle complex object structures, exclude sensitive data, or adapt the serialization format. While still functional, newer serialization techniques often offer more streamlined approaches in modern development.
