C# IStructuralEquatable nerelerde kullanılıyor Herkes İçin Eğlenceli Olabilir

Wiki Article

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.

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 .

That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.

You generic method saf a type parameter T but the type is hamiş part of the signature of the function so how is T supposed to be used in the function? Anyway, you sevimli use .Kupkuru tuples or anonymous types to create hash codes by combining values but I am derece sure this answers your question.

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

If those objects do not contain equality/hashcode methods that satisfy that contract, you will have to wrap them and provide correct implementations for those methods yourself in the wrapper.

Doğrusu anlayacağınız “int” gibi, “bool” kadar kırat tipli bir kararsız kurmak istiyorsanız struct yapkaloriı tercih edebilirsiniz.

Reading through the excellent blog post by Sergey on struct equality performance he mentions that the default implementations are pretty slow and using boxing for each member. Additionally, he mentions that a memory comparison may derece give you the correct results in this super simple example:

I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer has 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.

Amma velakin bu inşaız class denli kompleks işlemler kucakin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle geçirmek yetiyorsa işte bu stil durumlarda struct yapısını tercih edebiliriz.

Do not send hash codes across application domains or processes. In some cases, hash codes may be computed on a per-process or per-application domain basis.

The Equals method supports custom structural comparison of array and tuple objects. This method in turn calls the comparer object's IEqualityComparer.Equals method to compare individual array elements or tuple components, starting with the C# IStructuralEquatable Temel Özellikleri first element or component.
