Hi there, In Jeffrey Richter's recent book, Applied .NET Framework programming, Page 156, he demonstrated how to implement Equals for a reference type whose base class overrides Object's Equals. He wrote this, // let the base type compare its fields if (!base.Equals(obj)) return false; ... // If the objects are of different types, they can't be equal if (this.GetType() != obj.GetType()) return false; ... However, if the base class implements its Equals in the similar way, since GetType is not virtual, then either base's (this.GetType() != obj.GetType()) or the derived class's one must evaluate to false. Hence the derived class's Equals will always return false. Do I miss anything? TIA, Yong
