Description
Returns an integer containing the hash code.
By default, calling GetHashCode on an object returns an integer representing the virtual address at which the object is stored.
- Notes:
- GetHashCode is supposed to be overridden in user-derived classes, to provide consumer objects with an integer hash code representation.
- The sign of the hash code depends on the address of the particular object instance. Negative hash code can appear for object instances that reside at higher memory locations.
