Programlama dillerinde en mühim OOP(Object Oriented Programing) konstrüksiyonlarından olan class örgüsına nazaran daha basit düzeyde aksiyonlemler gerçekleştirmemizi sağlayıcı ve mukannen bir ekip engellemelerı yanında barındıran struct yapkaloriı C# diline özel ele alacağız.

I am trying to have struct birli a property in my class, and want to check to see if the struct is equal to the value I am trying to assign it to, before I go ahead and do so, so I am hamiş indicating the property katışıksız changed when it hasn't, like so:

I want to know what for is StructuralComparisons Class present in System.Collections used and also how is it used?I have no idea how should I use it!! Smallest help would be appreciated.

. The best example of this is arrays, which with .Kemiksiz 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 C# StructuralComparisons Kullanımı with the same values in each position. Here's an example:

The IStructuralComparable interface enables you to implement customized comparisons for collection members. That is, you gönül define precisely what it means for one collection object to precede, follow, or occur in the same position in the sort order kakım a second collection object.

Being able to specify IStructuralEquatable/IStructuralComparable in such cases is C# StructuralComparisons Kullanımı actually useful.

IEqualityComparer A predefined object that is used to compare two collection objects for structural equality.

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