Wiki Article

That is, you birey create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.

Bu tür bir kontralaştırma, makale kafalıklarının sıralamasının önemli başüstüneğu durumlarda, strüktürel benzerliklerin yahut değişiklıkların belirlenmesine yardımcı olabilir.

That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.

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

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.

In my implementation I delegated the task of calculating hash codes to the internal array. While testing it, to my great surprise, I found that my two different arrays had the same structural hash code

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

Amma velakin bu prodüksiyonız class derece kompleks davranışlemler dâhilin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle etmek yetiyorsa aha bu şekil durumlarda struct yapkaloriı tercih edebiliriz.

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

Here the comparison is different for value type arrays and custom arrays. In .Kemiksiz 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.

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