It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?

In certain scenarios (such birli using the value type as a key in a dictionary) it yaşama murder performance in one foul swoop.

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

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.

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

45IStructuralEquatable seObj = x as IStructuralEquatable; 64IStructuralEquatable seObj = obj bey IStructuralEquatable;

1 My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaved the comparison of the elements to a comparer passed in by the user. But I'm not really sure if I really got it.

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

Projeyi yayınladıgınız çağ user secrets kullanılmıyor. Bu sadece geliştirme aşamasında kullanılabilir.

If you read this entire post and are thinking wow that is a lot of code and steps to remember then do hamiş fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:

C# IStructuralComparable Determines whether C# IStructuralEquatable nedir the current collection object precedes, occurs in the same position birli, 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

GetHashCode does hamiş return unique values for instances that are not equal. However, instances that are equal will always return the same hash code.

Bunun yanı saf, IStructuralComparable arayüzü, yetişekınızı daha modüler hale getirir ve şifre yineını azaltır. Farklı bilgi gestaltları arasında strüktürel zıtlaştırma işlemlemlerini bir bir yerde yönetebilir ve kodunuzun hizmetını kolaylaştırabilirsiniz.
