Detaylar, Kurgu ve C# IStructuralEquatable Temel Özellikleri

Wiki Article

comparer IEqualityComparer An object that determines whether the current instance and other are equal.

= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.

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:

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

Ee sav gelimi struct dokumasında da new operatörünü kullanırsak eğer ha alakalı yapıdan bir nesne üretilecektir lakin struct bir valör tipli değişici örgüsında başüstüneğundan dolayı o nesne belleğin Stack kısmında muhafaza edilecektir.

Structural equality means that two objects are equal because they have equal values. It differs from reference equality, which indicates that two object references are equal because they reference the same physical object. The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

What does IEquatable buy C# IStructuralEquatable Nasıl kullanılır you, exactly? The only reason I emanet see it being useful is when creating a generic type and forcing users to implement and write a good equals method.

We hayat also make our own container play well with these other containers by implementing these interfaces.

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

You observations does derece conflict with the documentation and there is no bug in the implementation.

Specifically, I do not know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
