System. Object

All types must ultimately inherit from the predefined system. Object type. It can be seen that the object is a type name defined in the system namespace. This object is the root of all other types, thus ensuring that each type of instance has a minimum Behavior Set. In particular, the system. Object type is used to do the following:
1: Compare the equality of the two instances
2: Get the hash code of the Instance
3: query the real type of an instance
4: Execute the instance's shortest copy (by bit or bitwise copy)
5. Get a string representation of the current status of the Instance Object
