If two objects compare kakım equal, the GetHashCode method for each object must return the same value. However, if two objects do derece compare bey equal, the GetHashCode methods for the two object do hamiş have to return different values.

= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.

Let us derece forget about additional operators and not just relying on Equals. We can implement the == and != operators easily:

The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.

The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .

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.

Kemiksiz on a certain C# IStructuralEquatable nedir platform, I'm compelled to issue the standard warning derece to rely on the values of hashcodes or how they are computed, since it is not guaranteed to be the same across updates or platforms.

Now that our struct is immutable the actual issue comes up when you need to compare these values. When I started to write the code to fix the bug I just decided that "hey I have the old values, I hayat just compare each of them":

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.

Bunun üstı keşik, IStructuralComparable arayüzü, izlenceınızı henüz modüler hale getirir ve harf tekrarını azaltır. Farklı bilgi kuruluşları arasında strüktürel mukabillaştırma sorunlemlerini vahit bir yerde yönetebilir ve kodunuzun hizmetını kolaylaştırabilirsiniz.
