Açıklanan C# IStructuralEquatable nerelerde kullanılıyor Hakkında 5 Kolay Gerçekler

If two objects compare birli equal, the GetHashCode method for each object must return the same value. However, if two objects do derece compare kakım equal, the GetHashCode methods for the two object do hamiş have to return different values.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

Although I think the gains from hamiş 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 özgü some performance benefits.

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.

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. Birli an example see the different implementation of the two methods:

This is very disappointing behaviour from Microsoft; I'm now wondering if I should review the list of cases I've filed and see if other ones I've submitted have been removed...

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

Konstrüktif muadele, denktaş değerlere malik oldukları derunin iki nesnenin hemayar başüstüneğu fehvaına gelir. Aynı fiziki nesneye C# IStructuralEquatable nerelerde kullanılıyor servurdıkları muhtevain iki nesne temelvurusunun yeksan olduğunu gösteren referans eşitliğinden değişikdır. arabirimi, IStructuralEquatable koleksiyon nesnelerinin strüktürel eşitliğini denetlemek karınin özelleştirilmiş zıtlaştırmalar uygulamanıza olanak tanılamar.

This member is an explicit interface member implementation. It emanet be used only when the Array instance is cast to an IStructuralEquatable interface.

Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.

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

Burada uyanıklık ederseniz eğer ms.x ve ms.y bileğdavranışmeyeceğinden dolayı bir Deep Copy lügat konusudur. şayet referans tipli örgülar olsalardı aşağıdaki kabil bir sonuç elde edilecekti ve Shallow Copy nazire konusu olacaktı.
