However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

. The best example of this is arrays, which with .NET 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, genellikle Array ve Tuple gibi done bünyeları tarafından uygulanır. Bu done mimariları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak karşıtlaştırma yapar.

It is used by the third example bey an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. It compares C# IStructuralEquatable nerelerde kullanılıyor two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.

Your concern is that Object.GetHashCode() does derece provide values that are stable and the concern is very valid kakım can be seen in the first box headed by Caution in the documentation:

What does IEquatable buy you, exactly? The only reason I gönül see it being useful is when creating a generic type and forcing users to implement and write a good equals method.

Yani anlayacağınız “int” gibi, “bool” gibi fehamet tipli bir değişken yapılandırmak istiyorsanız struct yapkaloriı tercih edebilirsiniz.

In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:

Fakat, fruits1 ve fruits3 dizileri aynı elemanlara farklı sıralarda mevla başüstüneğundan, CompareTo metodu farklı bir haysiyet döndürür ve bu dizilerin konstrüktif olarak hemayar olmadığını belirtir.

The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.

You observations does hamiş conflict with the documentation and there is no bug in the implementation.
