Is it possible to give an unambiguous definition to the concept of “information”? more hot questions
ちょっと横道にそれますが、上記サンプルコード（構造体の例など）にちょっと見慣れない形式のコードがいくつか見受けられます。
Cevapla ↓ 21 سعید محمد 3 sene önce I love your blog.. very nice colors & theme. Did you create this website yourself or did you hire someone to do it for you?
IEqualityComparer is an interface which is used to find whether an object is equal or not. We will see this in a sample where we have to find the distinct objects in a collection. This interface will implement the method Equals(T obj1,T obj2).
I particularly feel that the GetHashCode() could do with some improvement, because it doesn't give unique values for objects with different reference objects nested further.
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
I would say that the best use would be when you need to plug in different equality rules for a certain algorithm. Much in the same way that a sorting algorithm might accept an IComparer, a finding algorithm might accept an IEqualityComparer
Comparing types is optional and depends on your inheritance structure, but in this case, if C# IEqualityComparer Temel Özellikleri ve Kullanımı the two players aren’t the same type, then they are hamiş equal.

– Eric Lippert Commented Apr 8, 2013 at 16:01 @EricLippert: What difficulties would arise if one allowed return type to be considered in method overloading only in cases where the return type was either being coerced to a particular type, or was passed to a method where all overloads of proper arity had the same type for that parameter (e.
ümit ederim bilgi meşbu bu makale, C# ve .Kupkuru geliştiricilerine rehberlik ederken ilham verici olmuştur!
According C# IEqualityComparer Temel Özellikleri ve Kullanımı to this thinking, both types should implement IEquatable, because it doesn't seem likely that there are other meaningful ways of doing an equality test.
Hepimiz Box Listemizi istediğimiz şeylere bakılırsa kategorize geçirmek istediğimiz için kendimize bir kıstas belirlememiz gerekiyor bunu bizim bağırsakin IEqualityComparer Interface’i yapıyor. Dictionary’imizi oluştururken IEqualityComparer sayesinde oluşturduğumuz Class’ın instance’sını ekliyoruz. Sonrasında Dictionary teker tekerlek gelen verilere bizim verdiğimiz algoritmaya C# IEqualityComparer nedir bakılırsa bakıyor. Öncelik olarak oluşturduğumuz Class’da ki GetHashCode()’ a gidiyor oradan HashCode’u tuzakıyor eğer C# IEqualityComparer Kullanımı önceki eklediği Key’lerde bu HashCode yoksa direkt olarak eklemesini strüktüryor.
Or if you need to change how C# IEqualityComparer Nasıl Kullanılır the comparer sorts, that you have to change them all? Lets say you do that comparison in 500 places, some in 3rd party code, now you have a maintenance nightmare.
