C # + arcengine serialization and deserialization of AE objects

During the AE development process, some objects must be temporarily stored, such as element, layer, map, and symbol. arcengine provides methods for serializing objects to save this information. All serializable objects support the ipersiststream interface (For details, refer to the help group documentation ). ixmlstream is also an important interface. for more information, see the help documentation.

 

This article is inspired by the technical documents of wall daniu.
