public override int GetHashCode()

Public Overrides Function GetHashCode As Integer

public:
virtual int GetHashCode() override

abstract GetHashCode : unit -> int 
override GetHashCode : unit -> int 

Return Value

Note that this breaks the normal usage of GetHashCode because it doesn't return the hash code of this object, it returns the calculated hash code of the fields that have been appended.

This means that objects of this class should never be put into hash sets or other collections that rely on the GetHashCode contract.
