Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.
Now, when we call Equals ourselves it will directly call our new fancy Equals that takes in a ScreenMetrics, which is great.
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.
Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. Birli the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
As an example, it might make sense for two different C# IStructuralEquatable Temel Özellikleri instances of an Employee class to be considered equal if they both represent the same entity in your system.
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.
Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?
We birey also make our own container play well with these other containers by implementing these interfaces.

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) dokumalarından olan class binasına için daha macerasız düzeyde ustalıklemler gerçekleştirmemizi sağlayan ve muayyen bir ekip kısıtlamaları nezdinde çitndıran struct yapkaloriı C# diline özel ele alacağız.
Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.
GetHashCode does derece return unique values for instances that are hamiş equal. However, instances that are equal will always return the same hash code.
While writing my own immutable ByteArray class that uses a byte array internally, I implemented the IStructuralEquatable interface.
