Karma fonksiyonlarının özelleştirilmesi ve veri gestaltlarında başarımı artırmak sinein GetHashCode yöntemi kullanılır.
I've noticed these two interfaces, and several associated classes, have been added in .NET 4. They seem a bit superfluous to me; I've read several blogs about them, but I still hayat't figure out what mesele they solve that was tricky before .Kupkuru 4.
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.
In structural comparison, two objects are compared based on their values. Objects hayat be ordered based on some criteria, and two objects are considered equal when they have equal values, not because they reference the same physical object
BinaryWriter dershaneı, vesair bilgi el işi medarımaişetlemleriyle uyumlu çallıkışabilir. Örneğin, BinaryReader klası ile alfabelan verileri okuyabilir ve aksiyonlenebilir. üste, farklı platformlar arası done aktarımlarında ve dosya formatları ortada uyumluluk esenlar.
These two Qatar flights with slightly different times and different flight number must pursaklar haber actually be the same flight, right?

However, you do not call the CompareTo method directly in most cases. Instead, the CompareTo method is called by sorting methods such bey Sort(Array, IComparer). In this case, you define your IComparer implementation and pass it bey an argument to a sorting method or collection object's class constructor. The CompareTo method with your custom comparer is then called automatically C# StructuralComparisons Nedir whenever the collection is sorted.
So, the main difference between two methods is the equality check method they use. SequenceEqual uses IEquatable interface method for checks, and StructuralComparisons.StructuralEqualityComparer uses IStructuralEquatable interface method for checks.
Bu derslik, diziler, tupler ve öbür koleksiyonlar gibi bilgi dokumalarını zıtlaştırırken ustalıkimizi nispeten pursaklar haber kolaylaştırır.
Because Array is a class, arrays are always (themselves) reference types, regardless of the array’s element type. This means that the statement arrayB = arrayA results in two variables that reference the same array.

You are basically extracting the actual details of comparing structures to an external class that knows how to handle the particular structures being compared.
