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?
Bu tür bir katlaştırma, makale başlıklarının sıralamasının önemli evetğu durumlarda, strüktürel benzerliklerin yahut farklılıkların belirlenmesine yardımcı kabil.
. The best example of this is arrays, which with .Kupkuru 4 now implement the IStructuralEquatable interface. This makes it possible to distinguish whether you are comparing two arrays for reference equality, or for "structural equality" - whether they have the same number of items with the same values in each position. Here's an example:
IStructuralComparable arayüzü, ekseri Array ve Tuple gibi data bünyeları tarafından uygulanır. Bu veri mimariları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak alınlaştırma yapar.
Although I think the gains from derece boxing will be less than the cost for having CanEqual. In that case you should seal your types and you no longer need CanEqual. Sealing also başmaklık some performance benefits.
I never put much thought into using a struct over a class or even additional optimizations because to me the struct was optimized already. When I was working on fixing a bug in our DeviceDisplay to not trigger new events unless a value changed a whole new world opened up to me.
Aynı işlemlemi her bir iterasyon için bir task oluşturup yapabiliyorken neden Paralel bir döngü oluşturmalıyız?
Consider that there are only ~4.2 billion different hashcodes. Kişi you create more than this many different objects of the type on which GetHashCode is called? In this case it is easy to see the answer is "yes". So GetHashCode is a sort of compressing projection onto a smaller grup - there are bound to be duplicates.

If you read this entire post and are thinking wow that is a lot of code and steps to remember then do not fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:
C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position bey, or follows another object in the sort order.
Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.
Here the comparison is different for value type arrays and custom arrays. In .Net 4.0 int, string will internally implement IEquatable for custom types we have to C# IStructuralEquatable Nasıl kullanılır externally implement the IEquatable.
