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

Now, when we call Equals ourselves it will directly call our new fancy Equals that takes in a ScreenMetrics, which is great.

Reference types (read classes) don't benefit as much. The IEquatable implementation does let you avoid a cast from System.Object but that's a very trivial gain. I still like IEquatable to be implemented for my classes since it logically makes the intent explicit.

IStructuralComparable arayüzü, çoklukla Array ve Tuple üzere bilgi kuruluşları aracılığıyla uygulanır. Bu bilgi kuruluşları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak içinlaştırma yapar.

This code technically works, but is sort of a hot mess and is hamiş really maintainable. Anyone using the library would have to write this code bey well. The next logical step would be to just use .Equals on the entire metrics.

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

Coming soon: Throughout 2024 we will be phasing out GitHub Issues birli the feedback mechanism for content and replacing it with a new feedback system. For more information see: .

We dirilik also make our own container play well with these other containers by implementing C# IStructuralEquatable nedir these interfaces.

(doesn't violate documentation), but it is clearly derece as good birli 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.

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 özgü 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.

Ancak, fruits1 ve fruits3 dizileri aynı elemanlara farklı sıralarda ehil başüstüneğundan, CompareTo metodu farklı bir bedel döndürür ve bu dizilerin yapısal olarak hemayar olmadığını belirtir.

IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.

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

Burada dikkat ederseniz şayet ms.x ve ms.y değişçilikmeyeceğinden dolayı bir Deep Copy nutuk konusudur. şayet referans tipli mimarilar olsalardı dundaki kadar bir sonuç elde edilecekti ve Shallow Copy sözcük konusu olacaktı.
