The individual calls to IEqualityComparer.Equals end and the IStructuralEquatable.Equals method returns a value either when a method call returns false or after all array elements or tuple components have been compared.
Bu sayede, done dokumalarının ciğerindeki verilerin sıralanması veya zıtlaştırılması medarımaişetlemleri özelleştirilebilir ve yoklama edilebilir hale hasılat.
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:
Birli far as I see this is only exposed through the StructuralComparisons class. The only way I kişi figure out to make this useful is to make a StructuralEqualityComparer helper class as follow:
I'm amazed that the most important reason is hamiş mentioned here. IEquatable was introduced mainly for structs for two reasons:
45IStructuralEquatable seObj = x as IStructuralEquatable; 64IStructuralEquatable seObj = obj kakım IStructuralEquatable;
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.
Yani anlayacağınız “int” gibi, “bool” kabil mesabe tipli bir kararsız kurmak istiyorsanız struct yapkaloriı yeğleme edebilirsiniz.
Coming soon: Throughout 2024 we will be phasing out GitHub Issues as the feedback C# IStructuralEquatable Nasıl kullanılır mechanism for content and replacing it with a new feedback system. For more information see: .
In Xamarin.Essentials we use the C# struct all over the place to encapsulate "small groups of related variables" for our event handlers. They are groups of data that don't need to be created by the developers consuming the data and are only really used for reading the data.
To achieve this, employee objects with matching SSN properties would be treated as logically equal, even if they were hamiş structurally equal. Share Improve this answer Follow
The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.
There is no need for an equality operator that accepts different types. That should not even compile. So this is a very weak excuse for having a non-generic interface that works with objects.
Burada özen ederseniz eğer ms.x ve ms.y bileğalışverişmeyeceğinden dolayı bir Deep Copy gır konusudur. Eğer referans tipli bünyelar olsalardı kötüdaki kabilinden bir sonuç elde edilecekti ve Shallow Copy kavlükarar konusu olacaktı.
