If two objects compare birli equal, the GetHashCode method for each object must return the same value. However, if two objects do not compare birli equal, the GetHashCode methods for the two object do hamiş have to return different values.

Let us hamiş forget about additional operators and not just relying on Equals. We kişi implement the == and != operators easily:

If two objects compare as equal, the GetHashCode method for each object must return the same value. However, if two objects do derece compare kakım equal, the GetHashCode methods for the two object do not have to return different values.

After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.

Now that our struct is immutable the actual issue comes up when you need to compare these values. When I started to write the code to fix the bug I just decided that "hey I have the old values, I kişi just compare each of them":

There is no need for an equality operator that accepts different types. That should hamiş even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

Specifically, I do hamiş know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
