Enum tanılamamlarken eğer rastgele bir eder verilmezse defaul olarak 0 dan kellelayarak boy bos vermeye adım atar . Burada
I'd also suggest small refactoring of FamilySelector class. Currently it holds the veri and performs comparison. Usually implementation of IEqualityComparer is a data-less class that just performs a comparison:
Another scenario where it may be useful to have an alternative means of comparison is when an object holds a reference to an instance a mutable type, but will never expose that instance to anything that might mutate it. In general, two instances of int[] that hold the same sequence of values will not be interchangeable, since it would be possible that in future one or both of them might be changed to hold different values.
$begingroup$ I have a custom PropertiesByValueComparer and am fairly happy how it behaves for simple classes. I haven't included comparing by fields yet. Is there anything that is blatantly yapan about this, or do you have other recommendations?
Kupkuru framework collections and where you want to add the same capability to your own collections. This will ensure that you are consistent with how the .NET framework C# IEqualityComparer Nasıl Kullanılır uses the interface.
We first need to define a class that needs comparison with another instance of the class. For this post, we’ll be using a Player class C# IEqualityComparer Temel Özellikleri ve Kullanımı with two properties.

BaseClass satisfies the first bound because it is larger than the first bound, and identical to the second bound.
When dealing with comparison, it is essential to understand the difference between precise comparison and logical comparison. Luckily for us, .NET saf the IEqualityComparer that is used by LINQ.
Bu harf, her 1 saniyede bir “Timer tetiklendi.” yazkaloriı konsola yazdıracaktır. Izlenceı sonlandırmak için herhangi bir tuşa basmanız yeterlidir.
I think the other post you mention is saying that EqualityComparer implements IEqualityComparer and IEqualityComparer, so you don't have to implement both the generic and non-generic interfaces if you derive from EqualityComparer.
The flexibility that this solution offers might be useful when one deals with the movie's sequel. The problem is that Julia Roberts plays two roles there: Tess Ocean and herself:
So now we know how to C# IEqualityComparer Nasıl Kullanılır use IEqualityComparer with LINQ and not make a mess of it. I hope this helps. However, I would like to push our ActorComparer a little further. Birli you might know, LINQ has an OrderBy(..) extension method that allows us to sort a collection C# IEqualityComparer nerelerde kullanılıyor according to some key.
If things don't seem to be working (such birli duplicate key errors when doing ToDictionary) put a breakpoint inside Equals to make sure it's being hit and make sure you have GetHashCode C# IEqualityComparer nedir defined (with override keyword).
