Devuelve un valor que indica si esta instancia equivale a un valor de Int32 especificado.

public:
 virtual bool Equals(int obj);

public bool Equals (int obj);

override this.Equals : int -> bool

Public Function Equals (obj As Integer) As Boolean

Parámetros

obj: Int32

Valor Int32 que se comparará con esta instancia.

Devoluciones

Boolean

true si el valor de obj tiene el mismo valor que esta instancia; en caso contrario, false.

Implementaciones

Equals(T)

Comentarios

Este método implementa la System.IEquatable<T> interfaz y funciona ligeramente mejor que Int32.Equals(Object) porque no tiene que convertir el obj parámetro en un objeto .

Notas a los autores de las llamadas

La resolución de sobrecarga del compilador puede tener en cuenta una diferencia aparente en el comportamiento de las dos Equals(Int32) sobrecargas del método. Si se define una conversión implícita entre el obj argumento y y Int32 el argumento no se escribe como Object, los compiladores realizan una conversión implícita y llaman al Equals(Int32) método . De lo contrario, llaman al Equals(Object) método , que siempre devuelve false si su obj argumento no es un Int32 valor. En el ejemplo siguiente se muestra la diferencia de comportamiento entre las dos sobrecargas del método. En el caso de los Bytevalores , Int16, SBytey UInt16 , la primera comparación devuelve true porque el compilador realiza automáticamente una conversión de ampliación y llama al Equals(Int32) método , mientras que la segunda comparación devuelve false porque el compilador llama al Equals(Object) método .
