Derleyici aşırı yükleme çözümlemesi, iki Equals(Object) yöntem aşırı yüklemesinin davranışında belirgin bir farka neden olabilir. bağımsız değişkeni ile Decimal arasında obj örtük bir dönüştürme tanımlanmışsa ve bağımsız değişken olarak Objectyazılmazsa, derleyiciler örtük bir dönüştürme gerçekleştirebilir ve yöntemini çağırabilirEquals(Decimal). Aksi takdirde, bağımsız değişkeni bir değer değilse obj her zaman döndüren false yöntemini çağırırlarEquals(Object).Decimal Aşağıdaki örnekte iki yöntem aşırı yüklemesi arasındaki davranış farkı gösterilmektedir. hem imzalı hem de imzasız türler de dahil olmak üzere tüm ilkel tam sayı türleri söz konusu olduğunda, derleyici otomatik olarak bir genişletme dönüştürmesi gerçekleştirip yöntemini çağırdığı Equals(Decimal) için ilk karşılaştırma döndürülüyortrue, ancak derleyici yöntemini çağırdığı Equals(Object) için ikinci karşılaştırma döndürülüyorfalse.

Equals(Decimal)

Source:: Decimal.cs

Source:: Decimal.cs

Source:: Decimal.cs

Bu örneğin ve belirtilen Decimal nesnenin aynı değeri temsil edip etmediğini belirten bir değer döndürür.

public:
 virtual bool Equals(System::Decimal value);

public bool Equals (decimal value);

override this.Equals : decimal -> bool

Public Function Equals (value As Decimal) As Boolean

Parametreler

value: Decimal

Bu örnekle karşılaştırılacak bir nesne.

Döndürülenler

Boolean

true bu örneğe eşitse; eşit değilse value , false.

Uygulamalar

Equals(T)

Açıklamalar

Bu yöntem arabirimini uygular ve parametresini System.IEquatable<T> bir nesneye dönüştürmesi value gerekmediğinden biraz daha iyi Equals performans gösterir.

Örnek türünden daha az bit (daha dar) varsa value , bazı programlama dilleri parametrenin değerini daha fazla bit içeren bir değere dönüştüren örtük bir genişletme dönüştürmesi gerçekleştirir.

Örneğin, örnek türünün ve parametre türünün olduğunu Int32 Bytevarsayalım. Microsoft C# derleyicisi parametrenin değerini bir Int32 nesne olarak göstermek için yönergeler oluşturur, ardından örneği ve parametre gösterimini Int32 karşılaştırmak için bir Int32.CompareTo yöntem oluşturur.

Derleyicinin sayısal türlerde örtülü genişleme dönüştürmeleri gerçekleştirip gerçekleştirmediğini belirlemek için programlama dilinizle ilgili belgelere bakın.
