Bu metod, dizilerin elemanlarını sırayla mukabillaştırır ve şayet diziler eşitse 0, bileğilse 0 haricinde bir şayan döner. Şimdi, bu sonucun ne kavrama geldiğini yoklama edelim:
The example then displays the elements in the array in unsorted order, sorts them by the third component (the population in 1970) and displays them, and then sorts them by the sixth component (the population in 2000) and displays them.

The fact that they've embedded those helper methods down into the base of object başmaklık caused lots of bugs in lots of code, they're available through intellisense but is sometimes hard to differentiate from the ones you actually want.
Horda, StructuralComparisons klasının farklı data mimarilarında kesinlikle kullanılabileceğini gösteren daha zait örnek bulunmaktadır:

Bu, özellikle tuplerin done dipı maslahatlemlerinde yahut algoritma kontralaştırmalarında kullanıldığı durumlarda yararlıdır.
Why do we have IStructuralComparable and IStructuralEquatable when there already exist the IComparable and IEquatable interfaces? The answer I would offer is that, in general, it's desirable to differentiate between reference comparisons and structural comparisons.
The above C# StructuralComparisons Temel Özellikleri implementaiton causes boxing, which bey described by Microsoft is "computationally expensive". Especially since you could just compare the 4 ints that your struct consists of.
Bu lahika örneklerde, StructuralEqualityComparer kullanarak dizilerin hemayar olup olmadığını arama ediyoruz ve StructuralComparer kullanarak diziler ortada mukabillaştırma mimariyoruz. Bu örnekler, StructuralComparisons dershaneının ne derece esnek ve kullanışlı olduğunu göstermektedir.
Similarly, two distinct arrays will always fail an equality test—unless you use a custom equality comparer. Framework 4.0 introduced one for the purpose of comparing C# StructuralComparisons Nedir elements in arrays which you yaşama access via the StructuralComparisons type.
And as a result, default equality checks need two of the compared items C# StructuralComparisons Kullanımı to be the same type but StructuralEqualityComparer doesn't require them to be same type. As the name suggests it is supposed to compare contents.
Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals can't be overridden and always compares by reference.
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.
