You get a nice simple bool Equals(T other) function and there's no messing around with casting or creating a separate class.
Hackathon yarışmamalarına, uygulayım bilimi meydanında kariyer yapmayı hedefleyen ya da bu alanda deneyime iye olan millet sıkılabilir.
Birli far as 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 has similar functionality to the above mentioned .

The first is the idea of precise equality. Given two references to objects, do the two references point to the same location in memory? Programming languages are suited for this kind of comparison, and .NET comes with many prebuilt operators to handle this case.
独自の型をコレクションの要素として利用する際には、次のことを考慮して設計しましょう
However you should have some good pre-checks within GetHashCode to avoid unneccessary calls to this slow method.
According to the IEqualityComparer code example provided by microsoft, you will want to use the new keyword (so hiding the C# IEqualityComparer Temel Özellikleri ve Kullanımı Equals implementation of the object) for implementing Equals.
In theory, there is only one sensible way of comparing two instances of either type: They are equal if the X and C# IEqualityComparer Nasıl Kullanılır Y properties in both instances are equal.
The dictionary is recreated with an equality comparer that C# IEqualityComparer nedir defines equality in a different way: Two boxes are considered equal if their volumes C# IEqualityComparer nerelerde kullanılıyor are the same.

If the code is so hard to analyze that you have to write a backtracking algorithm to get it right, odds are good that the code should be written more clearly in the first place. If the compiler sevimli't make sense of it without backtracking, neither kişi the human reader.
Bey we saw above, it doesn’t take much code. Kakım our model evolves, we’ll likely have C# IEqualityComparer Temel Özellikleri ve Kullanımı to extend our comparers, so always thinking about what “equal” means now and what it could mean in the future is a valuable exercise.
