Gibt einen Wert zurück, der angibt, ob diese Instanz einem angegebenen Objekt oder Int64.

Name	Beschreibung
Equals(Int64)	Gibt einen Wert zurück, der angibt, ob diese Instanz einem angegebenen Int64 Wert entspricht.
Equals(Object)	Gibt einen Wert zurück, der angibt, ob diese Instanz einem angegebenen Objekt entspricht.

Gibt einen Wert zurück, der angibt, ob diese Instanz einem angegebenen Int64 Wert entspricht.

public:
 virtual bool Equals(long obj);

public bool Equals(long obj);

override this.Equals : int64 -> bool

Public Function Equals (obj As Long) As Boolean

Parameter

obj: Int64

Ein Int64 Wert, der mit dieser Instanz verglichen werden soll.

Gibt zurück

Boolean

true if obj has the same value as this instance; otherwise, false.

Implementiert

Equals(T)

Hinweise

Diese Methode implementiert die System.IEquatable<T> Schnittstelle und führt etwas besser aus, als Equals weil der Parameter nicht in ein Objekt konvertiert obj werden muss.

Hinweise für Aufrufer

Die Compilerüberladungsauflösung kann einen offensichtlichen Unterschied im Verhalten der beiden Equals(Int64) Methodenüberladungen ausmachen. Wenn eine implizite Konvertierung zwischen dem obj Argument und einem Int64 definiert ist und das Argument nicht als Typ Objecteingegeben wird, führen Compiler eine implizite Konvertierung durch und rufen die Equals(Int64) Methode auf. Andernfalls rufen sie die Equals(Object) Methode auf, die immer zurückgegeben wird false , wenn das obj Argument kein Int64 Wert ist. Das folgende Beispiel veranschaulicht den Unterschied im Verhalten zwischen den beiden Methodenüberladungen. Bei den Werten , Byte, , SByte, Int16 UInt16und Int32 Werten gibt der erste Vergleich zurückUInt32, da der Compiler automatisch eine Erweiterungskonvertierung durchführt und die true Methode aufruft, während der zweite Vergleich zurückgegeben Equals(Int64) wird, da der Compiler die false Methode aufruft.Equals(Object)
