2 Dakika Kural için C# IStructuralEquatable Nasıl kullanılır

The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is not reason enough to approve a correction edit.

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

This is really amazing code and works great for .Kupkuru Standard libraries. If you are in a .Kupkuru 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 derece just compare references or individual values.

Bildiğiniz üzere new operatrisü classlarda kullanıldığı ahit ait classtan bir nesne istem 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 as an argument to the Equals method, you kişi define a custom equality comparison for the array C# IStructuralEquatable Nasıl kullanılır or collection.

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...

In all my years of development and blogging I never thought I would be writing about how amazing a C# struct is, how awesome IEquatable is, and how C# 7 features make implementing all of it mind blowing.

That is, you güç 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 özgü two members: Equals, which tests for equality by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.

Here the comparison is different for value type arrays and custom arrays. In .Kemiksiz 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.

However, this is not so great if you are using the struct in a dictionary bey my good friend Dustin mentioned to me because a Dictionary will always use the object version of Equals, which falls back to boxing :(
