comparer IEqualityComparer An object that determines whether the current instance and other are equal.
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:
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. Kakım the output from the example shows, the first three method calls return true, whereas the fourth call returns false.

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.

In Xamarin.Essentials we use the C# C# IStructuralEquatable nerelerde kullanılıyor struct all over the place to encapsulate "small groups of related variables" for our event handlers. They are groups of veri that don't need to be created by the developers consuming the veri and are only really used for reading the data.
C# IStructuralEquatable Defines methods to support the comparison of objects for structural equality.
He, makalede nekais olabilir. Bunu eleştiri olarak akseptans ediyorum. Fonksiyonel programlamada struct kullanılmasının nedenini bile bilmiyor, performans ve diğer mevzular hakkında da herhangi bir düşünce çitndırmıdeğerlendirme. Siz biliyorsanız lütfen aydınlatır mkaloriız?
Here the comparison is different for value type arrays and custom arrays. In .Net 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.
