If equality is hamiş needed for the derived class you emanet skip IEquatable but you need to override the CanEqual to prevent it being equal with base classes (unless of course they should be considered equal).
In certain scenarios (such as using the value type birli a key in a dictionary) it güç murder performance in one foul swoop.
If you want to implement IEquatable in a class hierarchy you emanet use the following pattern. It prevents derived (including sibling) classes from being equal.

If two objects compare birli equal, the GetHashCode method for each object must return the same value. However, if two objects do not compare birli equal, the GetHashCode methods for the two object do hamiş have to return different values.

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.

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.
Kemiksiz on a certain ortam, I'm compelled to issue the standard warning not to rely on the values of hashcodes or how they are computed, since it is derece guaranteed to C# IStructuralEquatable Temel Özellikleri be the same across updates or platforms.
Olur, makalede eksiklikler olur. Bunu eleştiri olarak onaylama ediyorum. Işlevsel programlamada struct kullanılmasının nedenini de bilmiyor, başarım ve gayrı konular için da herhangi bir görüş çitndırmıversiyon. Siz biliyorsanız lütfen aydınlatır mısınız?
Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?
While writing my own immutable ByteArray class that uses a byte array internally, I implemented the IStructuralEquatable interface.
