Určuje, zda je zadaný objekt roven aktuálnímu SortKey objektu.

public:
 override bool Equals(System::Object ^ value);

public override bool Equals (object? value);

public override bool Equals (object value);

override this.Equals : obj -> bool

Public Overrides Function Equals (value As Object) As Boolean

Parametry

value: Object

Objekt, který chcete porovnat s aktuálním SortKey objektem.

Návraty

Boolean

true pokud je value parametr roven aktuálnímu SortKey objektu, falsev opačném případě .

Výjimky

ArgumentNullException

value je null.

Poznámky

Dva SortKey objekty jsou považovány za rovny, pokud jsou jejich KeyData vlastnosti rovny.

Tato metoda přepíše Object.Equals.
