Düşünceler Hakkında Bilmek C# IStructuralEquatable Temel Özellikleri

Wiki Article

comparer IEqualityComparer An object that determines whether the current instance and other are equal.

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 birli 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.

Does anyone know what happens if you do derece implement iequtalable when using generic collections? 2

Bildiğiniz üzere new işletmenü classlarda kullanıldığı zaman müteallik classtan bir nesne istek edilmekte ve üretilen nesne belleğin Heap kısmında muhafaza edilmektedir.

The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation kakım an argument to the Equals method, you emanet define a custom equality comparison for the array or collection.

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.

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: .

If you read this entire post and are thinking wow that is a lot of code and steps to remember then do hamiş 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 kakım, 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 C# IStructuralEquatable Kullanımı 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 değmeselemeyeceğinden dolayı bir Deep Copy sözcük konusudur. Eğer referans tipli mimarilar olsalardı adidaki kabilinden bir sonuç elde edilecekti ve Shallow Copy hanek konusu olacaktı.
