Microsoft'un teknoloji müptelaları yürekin sunmuş olduğu kibar bir platform olan Channel 9’da mevki alan Jump Start serisi, C# programlama dili öğrenmek isteyenler ciğerin harika bir bidayettır.
This way, you yaşama implement a test that fails if any properties are added. Of course, you'd have to add new properties to the array at the beginning. Kakım using reflection is an expensive operation from a performance point of view, I'd propose to use it in the test, not in the comparer itself if you need to compare lots of objects.
As far kakım best practices around using this interface for your own purposes. I would say that the best practice would be to use it when you are deriving or implementing a class that saf similar functionality to the above mentioned .
Because you need an instance and not just a method call you sevimli't let the generic type be inferred by the compiler (see this discussion) but have to do so when creating the instance:
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).

Bu özellik, sakat kullanıcılar dâhilin görüntülük kari yazılımlar yahut öbür yardımcı teknolojiler tarafından kullanılabilir.
You could possibly create a GenericComparer with a generic parameter which is constrained to be at least C# IEqualityComparer nerelerde kullanılıyor of base class which might get you closer to what you are trying to do. This would look like
This interface allows the implementation of customized equality comparison for collections. That is, you birey create your own definition of equality, and specify that this definition be used with a collection type that accepts the IEqualityComparer interface.
Elan C# IEqualityComparer Kullanımı ziyade veri C# IEqualityComparer Nasıl Kullanılır ciğerin Microsoft Learn’daki “C# 12'bile Neler Yeni” sayfasına ve Roslyn Özellik Durumu sayfasına delik atabilirsiniz. Siz de bu bekâretçi özellikleri deneyerek yazılım ihya deneyiminizi geliştirebilirsiniz.
When we make the inference from allPositions to IEnumerable we say "IEnumerable is covariant in T, so we hayat accept Position or any larger type
The Equals(T, T) method is reflexive, symmetric, and transitive. That is, it returns true if used to compare an object with itself; true for two objects x and y if it is true for y and x; and true for two objects x and z if it is true for x and y and also true for y and z.
However, choosing the more specific type Giraffe: return value dirilik implicitly be cast to a larger type Animal if needed; and a return type of IEnumerable implicitly casts to IEnumerable. And that's C# IEqualityComparer Kullanımı the most used variant interface. I wonder why the more general type was chosen?
İki sayı değişici tanımlıyoruz ve bunları out parametresiyle bir metodun içerisine atıyoruz. Bu metodumuz bizlere yekûn değeri olan iki sayı parametre döndürür.
