FontDescriptorGetHashCode Method

Return Value

Int32
The integer identifier that represents a unique number for each instance of a class.

For Equals and GetHashCode methods, an override should be completed together to match the logic; if Equals returns true, hashcodes should be the same; the same hashcodes do not always mean that objects are the same because of collisions; hashcodes should be formed on fields on which equality is based; sometimes the Equals method is taken from the object, but since pointers are compared, you still can use GetHashCode from here, while Equals can be overridden in the derived class.
