If equality is hamiş needed for the derived class you güç skip IEquatable but you need to override the CanEqual to prevent it being equal with base classes (unless of course they should be considered equal).

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

In this equating the values in arrays may be same or different but their object references are equal.

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 hamiş trigger new events unless a value changed a whole new world opened up to me.

So, I am apparently wrong kakım unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed set of values a requirement?

I've noticed these two interfaces, and several associated classes, have been added in .Kemiksiz 4. They seem a bit superfluous to me; I've read several blogs about them, but I still gönül't figure out what mesele they solve that was tricky before .NET 4.

Safi on a certain platform, I'm compelled to issue the standard warning derece to rely on the values of hashcodes or how they are computed, since it is not guaranteed to be the same across updates or platforms.

IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.

Just look at the default ValueType.Equals(object) code that gets called otherwise. It's an C# IStructuralEquatable Temel Özellikleri absolute performance killer that introduces boxing, type evaluation and finally falls back on reflection if any of the fields are reference types.

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