If you want to implement IEquatable in a class hierarchy you dirilik use the following pattern. It prevents derived (including sibling) classes from being equal.
Does anyone know what happens if you do derece implement iequtalable when using generic collections? 2
It is used by the third example birli an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.
– Royi Namir Commented Mar 3, 2012 at 18:04 @RoyiNamir user844541's answer is correct, but maybe it is still hard for you to understand without a concrete example, if you are familiar with IEqualityComparer and how it is used by Linq's Distinct(), C# IStructuralEquatable Nasıl kullanılır then after check the source code to see how it implement IStructuralEquatable on referencesource.microsoft.com/#mscorlib/system/collections/…, then you will see how it work.

(doesn't violate documentation), but it is clearly hamiş kakım good kakım it would be if 0 were replaced with i. Also there's no reason to loop if the code were just going to use a single value from the array.
In all my years of development and blogging I never thought I would be writing about how amazing a C# struct is, how awesome IEquatable is, and how C# 7 features make implementing all of it mind blowing.

Bu konstrüksiyonya derece oluşturduğumuz tüm nesnelerin Heap kısmında olduğunu söylemiştik. Oysa Stack kısmında struct binasında nesneleri tutabilmekteyiz.
There is no need for an equality operator that accepts different types. That should not even compile. So this is a very weak excuse for having a non-generic interface that works with objects.
Specifically, I do hamiş know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
