Definición

Espacio de nombres:

System

Ensamblado:

System.Runtime.dll

Source:

Tuple.cs

Devuelve un valor que indica si el objeto Tuple<T1,T2,T3,T4,T5,T6> actual es igual que el objeto especificado.

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

public override bool Equals (object? obj);

override this.Equals : obj -> bool

Public Overrides Function Equals (obj As Object) As Boolean

Parámetros

obj

Object

Objeto que se va a comparar con esta instancia.

Devoluciones

Boolean

true si la instancia actual es igual que el objeto especificado; en caso contrario, false.

Ejemplos

En el ejemplo siguiente se define una matriz de sextuplas que contienen datos de población para Los Ángeles y Nueva York de 1960 a 2000. El primer componente de cada sextuple identifica la ciudad. Las primeras, terceras y cuartas sextuplas contienen datos para Nueva York. La primera sextupla es un duplicado del cuarto sextuple. La tercera sextupla identifica la ciudad como "Nueva York" en lugar de "Nueva York". Como se muestra en el ejemplo, solo la cuarta sextupla es igual a la primera sextuple.

Comentarios

El obj parámetro se considera igual a la instancia actual en las condiciones siguientes:

• Es un Tuple<T1,T2,T3,T4,T5,T6> objeto .

• Sus seis componentes son de los mismos tipos que la instancia actual.

• Sus seis componentes son iguales a los de la instancia actual. La igualdad viene determinada por el comparador de igualdad de objetos predeterminado para cada componente.
