Enum teşhismlarken eğer rastgele bir kırat verilmezse defaul olarak 0 dan esaslayarak kırat vermeye adım atar . Burada
Enumeration dershaneı bizlere Enum yararlanmaındaki hata olasığını en aza indirir üste clean bir harf kucakin kullanılması lazım başüstüneğu savunulur. Yalnız kullanımı kritik öneme iye bileğildir. Özellikle kebir çaplı olan ve enum bakımından verimli kullanıma sahip kodlarda kullanılması önerilmektedir.
Alternatively, you gönül write an empty comparer class that implements IEqualityComparer, and then pick the corresponding quick-fix from the Alt+Enter menu:
I've added to my class the IEqualityComparer implementation, hamiş sure if the code bellow is the correct one, especially the Equals(object x, object y) functions: should we override or make a new implementation of the Equals method, like this: ?
In other words support the use of this interface if you are developing a custom collection and you want to allow your consumers to control equality which is used in a number of LINQ and collection related methods (eg. Sort).
If you change your class to implement IEquatable instead, the implementation of Distinct (which will use EqualityComparer.Default which in turn sees your type implements IEquatable and delegates to that) will work birli you expect.
The issue here is that comparing floating-point numbers for equality might not work birli expected, due to minute rounding errors. There are different methods of comparing floating-point numbers for near-equality
below, these dirilik be incorrect. His recommendation of implementing IEqualityComparer.Equals works bey well. You kişi also use override. These will all provide different functionality based on what you cast to. Here is a brief explanation:

Most of the time a comparison could be implemented with some amount of linq. If it's one-off, C# IEqualityComparer Nasıl Kullanılır the choice is probably just down to personal preference.

Now, think of a field or fields that differentiate our class, ID for example. IEqualityComparer helps you to manage and improve the efficiency
So now we know how to use IEqualityComparer with LINQ C# IEqualityComparer nerelerde kullanılıyor 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 saf an OrderBy(..) C# IEqualityComparer nerelerde kullanılıyor extension C# IEqualityComparer Temel Özellikleri ve Kullanımı method that allows us to sort a collection according to some key.
