Açıklamalar
Bu yöntem arabirimini gerçekleştirir ve parametresini bir nesneye dönüştürmesi gerekmesi nedeniyle biraz daha System.IEquatable<T> Equals iyi performans obj
gösterir.
Ayrıca bkz.
Şunlara uygulanır
Equals(TimeSpan, TimeSpan)
Belirtilen iki örneğinin eşit olup olmadığını belirten bir TimeSpan değer döndürür.
public:
static bool Equals(TimeSpan t1, TimeSpan t2);
public static bool Equals (TimeSpan t1, TimeSpan t2);
static member Equals : TimeSpan * TimeSpan -> bool
Public Shared Function Equals (t1 As TimeSpan, t2 As TimeSpan) As Boolean
Parametreler
- t1
- TimeSpan
Karşılaştırılacak ilk zaman aralığı.
- t2
- TimeSpan
Karşılaştırılacak ikinci zaman aralığı.
Döndürülenler
