The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is hamiş reason enough to approve a correction edit.

In this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.

If you want to implement IEquatable in a class hierarchy you sevimli use the following pattern. It prevents derived (including sibling) classes from being equal.

Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals kişi't be overridden and always compares by reference.

Let us derece forget about additional operators and hamiş just relying on Equals. We güç implement the == and != operators easily:

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

I've noticed these two interfaces, and several associated classes, have been added in .Kupkuru 4. They seem a bit superfluous to me; I've read several blogs about them, but I still hayat't figure out what sıkıntı they solve that was tricky before .Kupkuru 4.

Task oluşturmanın nöbetlemci üzerinde maliyeti vardır ve çok kesik süren çalışmalemler bağırsakin bir task yapılandırmak genelde henüz yavaş çalışan uygulamalara vesile olabilir.

Each of your objects should use a hashcode based on the contents of the object. If you have a value type containing 3 ints, use those when computing the hash code. Like this, all objects with identical content will have the same hash code, independent of app domain and other circumstances.

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

The IStructuralEquatable interface supports only custom comparisons for structural equality. The IStructuralComparable interface supports custom structural comparisons for sorting and ordering.
