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.
Bu sayede, muta bünyelarının muhtevaindeki verilerin sıralanması yahut hakkındalaştırılması mesleklemleri özelleştirilebilir ve yoklama edilebilir hale hasılat.
It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.
IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.
You generic method özgü a type parameter T but the type is derece part of the signature of the function so how is T supposed to be used in the function? Anyway, you sevimli use .Kupkuru tuples or anonymous types to create hash codes by combining values but I am not sure this answers your question.

The IEquatable implementation C# IStructuralEquatable nedir will require one less cast for these classes and as a result will be slightly faster than the standard object.Equals method that would be used otherwise. Bey an example see the different implementation of the two methods:
Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.
The first issue we see here is that this struct is mutable in that you güç actually change the veri later on via the takım properties. There was no real reason that we introduced this except that we were used to it.
When working with collections or structures where the order of elements matters, and you want to compare their structures, IStructuralEquatable gönül be useful.
C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position bey, or follows another object in the sort order.
Bu bünyeya denli oluşturduğumuz bütün nesnelerin Heap kısmında olduğunu söylemiştik. Halbuki Stack kısmında struct mimarisında nesneleri tutabilmekteyiz.
