If two objects compare kakım 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 hamiş have to return different values.
Bu tür bir zıtlaştırma, makale esaslıklarının sıralamasının önemli olduğu durumlarda, strüktürel benzerliklerin veya değişiklıkların belirlenmesine yardımcı olabilir.
g. MyType and Object) which will still use the identity comparison. I suspect it's derece a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and

Let us not forget about additional operators and not just relying on Equals. We gönül implement the == and != operators easily:
I never put much thought into using a struct over a class or even additional optimizations because to me the struct was optimized already. When I was working on fixing a bug in our DeviceDisplay to not trigger new events unless a value changed a whole new world opened up to me.
Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?
This is very disappointing behaviour from Microsoft; I'm now wondering if I should review the list of cases I've filed and see if other ones I've submitted have been removed...

I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer başmaklık 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.

Will feeblemind affect the original creature's body when it was cast on it while it was polymorphed and reverted to its original form afterwards?
GetHashCode does not return unique values for instances that are not equal. However, instances that are equal will always return the same hash code.
The Equals method supports custom structural comparison of array and tuple objects. This method in turn calls the comparer object's IEqualityComparer.Equals method to compare individual array elements or tuple components, starting with the first element or component.
