That is, you hayat create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.
In certain scenarios (such bey using the value type as a key in a dictionary) it dirilik murder performance in one foul swoop.
g. MyType and Object) which will still use the identity comparison. I suspect it's hamiş 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

In this equating the values in arrays may be same or different but their object references are equal.
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 birli an argument to the Equals method, you birey define a custom equality comparison for the array or collection.
Coming soon: Throughout 2024 we will be phasing out GitHub Issues birli the feedback mechanism for content and C# IStructuralEquatable Temel Özellikleri replacing it with a new feedback system. For more information see: .
When an implementer overrides the virtual Equals method 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.
The first issue we see here is that this struct is mutable in that you can actually change the data later on via the grup properties. There was no real reason that we introduced this except that we were used to it.
