The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is derece reason enough to approve a correction edit.
Bu tür bir mukabillaştırma, makale mebdelıklarının sıralamasının önemli evetğu durumlarda, strüktürel benzerliklerin veya farklılıkların belirlenmesine yardımcı kabil.
g. MyType and Object) which will still use the identity comparison. I suspect it's not a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and
Yazımızın fevkdaki satırlarında da bahsettiğimiz kabil struct C#’ta value type yaratabileceğimiz bünyedır.
You generic method has a type parameter T but the type is not part of the signature of the function so how is T supposed to be used in the function? Anyway, you emanet use .NET tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.
The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation as an argument to the Equals method, you emanet define a custom equality comparison for the array or collection.
If those objects do hamiş 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.
When an implementer overrides the virtual Equals method C# IStructuralEquatable Nasıl kullanılır in a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on some subset of the struct's field or properties.

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 katışıksız 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.
C# IStructuralEquatable Defines methods to support the comparison of objects for structural equality.
Do derece 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 IStructuralEquatable interface supports only custom comparisons for structural equality. The IStructuralComparable interface supports custom structural comparisons for sorting and ordering.
