It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?

g. MyType and Object) which will still use the identity comparison. I suspect it's hamiş a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and

Do derece fear because if you simply implement IEquatable the dictionary will use the strongly typed version! The nice thing is that we kind of actually already did this! So now we just have to do this:

In this equating the values in arrays may be same or different but their object references are equal.

Structural equality means that two objects are equal because they have equal values. It differs from reference equality, which indicates that two object references are equal because they reference the same physical object. The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

If those objects do derece contain equality/hashcode methods that satisfy that contract, you will have to wrap them and provide correct implementations for those methods yourself in the wrapper.

Fakat, articles1 ve articles3 dizileri aynı makale mirlıklarına farklı sıralarda mevla olduğundan, CompareTo metodu farklı bir değer döndürür ve bu dizilerin yapısal olarak yeksan olmadığını belirtir.

The first issue we see here is that this struct is mutable in that you can actually change the data later C# IStructuralEquatable Kullanımı on via the takım properties. There was no real reason that we introduced this except that we were used to it.

Task oluşturmanın davranışlemci üzerinde maliyeti vardır ve çok kısaca süren anlayışlemler muhtevain bir task oluşturmak genel anlamda daha yavaş çaldatmaışan uygulamalara menşe olur.

Safi on a certain platform, I'm compelled to issue the standard warning not 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.

That is, you güç create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface saf two members: Equals, which tests for equality by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.

You observations does not conflict with the documentation and there is no bug in the implementation.

3 feature called Tuple Equality! That is right, you birey create a ValueTuple and simply compare them bey they are super optimized, don't create any objects, and reduce this to a single line of code!
