If I never ever use HashSet, should I still implement GetHashCode?

I never need to store objects in a hash table. The reason is twofold:

coming up with a good hash function is difficult and error prone.
an AVL tree is almost always fast enough, and it merely requires a strict order predicate, which is much easier to implement.

The Equals() operation on the other hand is a very frequently used function.

Therefore I wonder whether it is necessary to implement GetHashCode (which I never need) when implementing the Equals function (which I often need)?

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
