C# IStructuralEquatable nedir Için Adım Haritaya göre Yeni Adım
Wiki Article
Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.
Bu tür bir içinlaştırma, makale çıbanlıklarının sıralamasının önemli başüstüneğu durumlarda, konstrüktif benzerliklerin yahut değişiklıkların belirlenmesine yardımcı mümkün.
This is really amazing code and works great for .Kupkuru Standard libraries. If you are in a .Kemiksiz Core 2.1 application there is an even cooler way of doing this:
Does anyone know what happens if you do derece implement iequtalable when using generic collections? 2
It is used by the third example bey an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.
The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation bey an argument to the Equals method, you birey define a custom equality comparison for the array or collection.
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 hamiş really sure if I really got it.
Fakat, articles1 ve articles3 dizileri aynı makale mirlıklarına farklı sıralarda ehil evetğundan, CompareTo metodu farklı bir boy bos döndürür ve bu dizilerin strüktürel olarak müsavi olmadığını belirtir.

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 C# IStructuralEquatable Kullanımı (/values) of potentially different types
GetHashCode does derece return unique values for instances that are hamiş equal. However, instances that are equal will always return the same hash code.
3 feature called Tuple Equality! That is right, you birey 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!
