Bu tür bir hakkındalaştırma, makale başlıklarının sıralamasının önemli olduğu durumlarda, strüktürel benzerliklerin yahut farklılıkların belirlenmesine yardımcı olabilir.

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

Your concern is that Object.GetHashCode() does not provide values that are stable and the concern is very valid as kişi be seen in the first box headed by Caution in the documentation:

The IEquatable implementation will require one less cast for these classes and kakım a result will be slightly faster than the standard object.Equals method that would be used otherwise. Bey an example see the different implementation of the two methods:

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