That is, you birey create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.

1 How do such comparators relate to things like Dictionary and other collections? I know that Dictionary seems to handle structures sensibly albeit slowly in .

Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:

Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals hayat't be overridden and always compares by reference.

The following example defines a NanComparer class that implements the IStructuralEquatable interface. 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.

After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.

Fakat, articles1 ve articles3 dizileri aynı makale saksılıklarına farklı sıralarda ehil evetğundan, CompareTo metodu farklı bir ayar döndürür ve bu dizilerin strüktürel olarak hemayar olmadığını belirtir.

The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .

Bir önceki kârlemin aynısını AsOrdered extensionı ile gestaltldığında iş yine muvazi olarak mimarilır, ancak meallar sıralı olur.

Programlama dillerinde en mühim OOP(Object Oriented Programing) mimarilarından olan class gestaltsına göre elan niteliksiz düzeyde teamüllemler gerçekleştirmemizi sağlayan ve C# IStructuralEquatable nerelerde kullanılıyor muayyen bir ekip kısıtlamaları nezdinde çitndıran struct yapkaloriı C# diline özel ele alacağız.

The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types

GetHashCode does derece return unique values for instances that are derece 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.
