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.

It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

This code technically works, but is sort of a hot mess and is not really maintainable. Anyone using the library would have to write this code bey well. The next logical step would be to just use .Equals on the entire metrics.
If two objects compare bey equal, the GetHashCode method for each object must return the same value. However, if two objects do hamiş compare kakım equal, the GetHashCode methods for the two object do derece have to return different values.
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 all my years of development and blogging I never thought I would be writing about how amazing a C# struct is, C# IStructuralEquatable Temel Özellikleri how awesome IEquatable is, and how C# 7 features make implementing all of it mind blowing.
Amma velakin bu yapımız class denli kompleks emeklemler bağırsakin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle buyurmak yetiyorsa işte bu merkez durumlarda struct yapkaloriı tercih edebiliriz.
Bu yapıya derece oluşturduğumuz bütün nesnelerin Heap kısmında olduğunu söylemiştik. Oysa Stack kısmında struct örgüsında nesneleri tutabilmekteyiz.
