Why didn't Jimmy Neutron realize immediately when he read the note on the refrigerator that the note is phony, birli the note says "son or daughter..."?

Coming soon: Throughout 2024 we will be phasing out GitHub Issues kakım the feedback mechanism for content and replacing it with a new feedback system. For more information see: .

. The best example of this is arrays, which with .NET 4 now implement the IStructuralEquatable interface. This makes it possible to distinguish whether you are comparing two arrays for reference equality, or for "structural equality" - whether they have the same number of items with the same values in each position. Here's an example:

However, you do hamiş call the C# StructuralComparisons Kullanımı CompareTo method directly in most cases. Instead, the CompareTo method is called by sorting methods such birli Sort(Array, IComparer). In this case, you define your IComparer implementation and pass it kakım an argument to a sorting method or collection object's class constructor. The CompareTo method with your custom comparer is then called automatically whenever the collection is sorted.

StructuralEqualityComparer Gets a predefined object that compares two objects for structural equality.

The interface IStructuralEquatable was defined to allow a class to explicitly implement structural, rather than reference equality. Related classes include IStructuralComparable and StructuralComparisons.

Note that the example does derece directly call the CompareTo method. The method is called implicitly by the Sort(Array, IComparer) method for each tuple object in the array.

ianhays commented Oct 23, 2017 Definitely agree that the implementation above would be too slow. Could we instead just write a new StructuralComparer that didn't call to the nongeneric StructuralComparisons.StructuralEqualityComparer?

I've noticed these two interfaces, and several associated classes, have been added in .NET 4. They seem a bit superfluous to me; I've read several blogs about them, but I still yaşama't figure out what mesele they solve that C# StructuralComparisons Nedir was tricky before .Safi 4.

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