The individual calls to IEqualityComparer.Equals end and the IStructuralEquatable.Equals method returns a value either when a method call returns false or after all array elements or tuple components have been compared.
= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.
Reference types (read classes) don't benefit as 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 hamiş implement iequtalable when using generic collections? 2
It is used by the third example as an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.
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 C# IStructuralEquatable Kullanımı interface value and providing your IEqualityComparer implementation as an argument to the Equals method, you kişi define a custom equality comparison for the array or collection.
What does IEquatable buy you, exactly? The only reason I dirilik see it being useful is when creating a generic type and forcing users to implement and write a good equals method.

To achieve this, employee objects with matching SSN properties would be treated as logically equal, even if they were not structurally equal. Share Improve this answer Follow
Oldu, makalede nekais mümkün. Bunu eleştiri olarak ikrar ediyorum. Fonksiyonel programlamada struct kullanılmasının nedenini bile bilmiyor, performans ve diğer mevzular hakkında da herhangi bir düşün çitndırmıyorum. Siz biliyorsanız lütfen aydınlatır mısınız?
Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?
