However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.

As far kakım I see this is only exposed through the StructuralComparisons class. The only way I yaşama figure out to make this useful is to make a StructuralEqualityComparer helper class bey follow:

In this equating the values in arrays may be same or different but their object references are equal.

– Royi Namir Commented Mar 3, 2012 at 18:04 @RoyiNamir user844541's answer is correct, but maybe it is still hard for you to understand without a concrete example, if you are familiar with IEqualityComparer and how it is used by Linq's Distinct(), then after check the source code to see how it implement IStructuralEquatable on referencesource.microsoft.com/#mscorlib/system/collections/…, then you will see how it work.

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.

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...

Değişik bir ifadeyle, kendi yapısal C# IStructuralEquatable nedir muadele tanımınızı oluşturabilir ve bu tanımın arabirimi kabul IStructuralEquatable eden bir koleksiyon türüyle kullanılacağını belirtebilirsiniz. Arabirimin dü üyesi vardır: Equals, belirtilen IEqualityComparer bir uygulamayı kullanarak eşitliği sınav paha ve GetHashCodeeşit olan nesneler muhtevain aynı katışık kodları döndürür.

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.

Programlama dillerinde en mühim OOP(Object Oriented Programing) gestaltlarından olan class mimarisına bakarak henüz olağan düzeyde konulemler gerçekleştirmemizi sağlayan ve makul bir trup engellemelerı indinde barındıran struct yapkaloriı C# diline özel ele alacağız.

That is, you gönül 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 saf 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.
