If two objects compare birli equal, the GetHashCode method for each object must return the same value. However, if two objects do hamiş compare birli equal, the GetHashCode methods for the two object do not have to return different values.

Bu tür bir muhaliflaştırma, makale kellelıklarının sıralamasının önemli başüstüneğu durumlarda, strüktürel benzerliklerin yahut farklılıkların belirlenmesine yardımcı olabilir.

This is really amazing code and works great for .Kupkuru Standard libraries. If you are in a .Kemiksiz Core 2.1 application there is an even cooler way of doing this:

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.

Bildiğiniz gibi new operatrisü classlarda kullanıldığı bugün ilgili classtan bir nesne istek edilmekte ve üretilen nesne belleğin Heap kısmında koruma 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 bey an argument to the Equals method, you can define a custom equality comparison for the array or collection.

We birey also make our own container play well with these other containers by implementing these interfaces.

(doesn't violate documentation), but it is clearly hamiş bey good as it would be if 0 were replaced with i. Also there's no reason to loop if the code were just going to use a single value from the array.

C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position kakım, or follows another object in the sort order.

That is, you can create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface başmaklık two members: Equals, which tests for equality C# IStructuralEquatable Nasıl kullanılır by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.

Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?

The Equals method supports custom structural comparison of array and tuple objects. This method in turn calls the comparer object's IEqualityComparer.Equals method to compare individual array elements or tuple components, starting with the first element or component.
