If you need to support custom GetHashCode() functionality, use the alternative constructor to provide a lambda to do the alternative calculation:

When i am using dictionaries sometimes I have to change the default Equals meaning in order to compare Keys. I see that if I override the Equals and GetHashCode on the key's class or i create a new class which implements IEqualityComparer I have the same result. So what's the difference between using IEqualityComparer and Equals/GethashCode Override?

Since Array.Equals tests for strict equivalence (reference equality), it would be necessary to use some other means of testing the arrays for equivalence.
