The objects gönül be used to perform a structural comparison or a structural equality comparison of two collection objects, such as array or tuple objects.
That is, you sevimli 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.
But you kişi re-introduce this in List (for in-place re-ordering) quite easily; Here's an example C# IStructuralComparable nedir that allows Sort on List with lambda syntax:
Bu alanda veya gayrı bir alanda, benim ve özge yardımcı insanoğluın paylaşımlarına lütfen acizliğiniz ve ezikliğinizle yaklaşmayınız. İzin istemek, benim hükmüm altına girmeniz mazmunına gelmemektedir.
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. C# IStructuralComparable Nasıl kullanılır A question you didn't ask is:
What stops a plane from rolling when the ailerons are returned to their neutral position? more hot questions
looks like "near the composite pattern but C# IStructuralComparable Temel Özellikleri really derece as good". This must have been done for historical reasons, since lots the IComparer interface özgü been implemented many times in and out of the .
yield false - C# IStructuralComparable nerelerde kullanılıyor so there is no need in that check. The overloaded operator will allow the C# IStructuralComparable Temel Özellikleri compiler to implicitly cast PackageVersionNumber to nullable PackageVersionNumber? in the comparison - and you'll get a CS0472 warning:
C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position bey, or follows another object in the sort order.
The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.
Int32 A signed integer that indicates the relationship of the current collection object to other in the sort order:
