Ee laf gelimi struct bünyesında da new işletmenünü kullanırsak şayet ya alakadar yapıdan bir nesne üretilecektir ama struct bir haysiyet tipli değişici kuruluşsında olduğundan dolayı o nesne belleğin Stack kısmında korunum edilecektir.

I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer saf 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.

C# StructuralComparisons StructuralComparer get Gets a predefined object that performs a structural comparison of two objects.

The IEqualityComparer from input parameter is used, in here you input StructruralEqualityComparer but int does hamiş implement IStructruralEquatable, so it uses default comparer for int which is value equality.

The StructuralComparisons.StructuralEqualityComparer version require that the two collections gönül support the IStructuralEquatable interface. But I would expect that the later is faster if the two lists are uneven lengths.

Diziler, programlamada çoğunlukla kullanılan bilgi dokumalarıdır ve elemanlarının sıralı bir şekilde önlaştırılması gerekebilir. StructuralComparisons.StructuralComparer ve StructuralComparisons.

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.

Note that the example does hamiş directly call the CompareTo method. The method is called implicitly by the Sort(Array, IComparer) C# StructuralComparisons Kullanımı method for each tuple object in the array.

I'm trying to understand why they have different implementations, since they seem like perfect synonyms.

I just had a related question and saw that this question was never actually answered properly. There C# StructuralComparisons Temel Özellikleri is a difference between the structural and the sequence - the first comparison is deep and the second one is derece. This simple code demonstrates and produces True False:
