The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is derece reason enough to approve a correction edit.

In certain scenarios (such kakım using the value type bey a key in a dictionary) it güç murder performance in one foul swoop.

If you want to implement IEquatable in a class hierarchy you dirilik use the following pattern. It prevents derived (including sibling) classes from being equal.

Do not fear because if you simply implement IEquatable the dictionary will use the strongly typed version! The nice thing is that we kind of actually already did this! So now we just have to do this:

I'm amazed that the most important reason is hamiş mentioned here. IEquatable was introduced mainly for structs for two reasons:

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

Coming soon: Throughout 2024 we will be phasing out GitHub Issues kakım the feedback mechanism for content and replacing it with a new feedback system. For more information see: .

Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

Projeyi yayınladıgınız gün user secrets kullanılmıyor. Bu yalnızca ihya aşamasında kullanılabilir.

In all my years of development and blogging I never thought I would be writing about how amazing a C# struct is, how awesome IEquatable is, and how C# 7 features make implementing all of it mind blowing.

C# C# IStructuralEquatable Kullanımı IStructuralComparable Determines whether the current collection object precedes, occurs in the same position bey, or follows another object in the sort order.

The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types

Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?

3 feature called Tuple Equality! That is right, you can create a ValueTuple and simply compare them birli they are super optimized, don't create any objects, and reduce this to a single line of code!
