Valor Int16 que se va a comparar con esta instancia.

Devoluciones

Boolean

true es si obj tiene el mismo valor que esta instancia; de lo contrario, falsees .

Equals(T)

Comentarios

Este método implementa la System.IEquatable<T> interfaz y funciona ligeramente mejor que Equals 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(Int16) sobrecargas del método. Si se define una conversión implícita entre el obj argumento y y Int16 el argumento no se escribe como , Objectlos compiladores realizan una conversión implícita y llaman al Equals(Int16) método . De lo contrario, llaman al Equals(Object) método , que siempre devuelve false si su obj argumento no es un Int16 valor. En el ejemplo siguiente se muestra la diferencia de comportamiento entre las dos sobrecargas del método. En el caso de los Byte valores y SByte , la primera comparación devuelve true porque el compilador realiza automáticamente una conversión de ampliación y llama al Equals(Int16) método , mientras que la segunda comparación devuelve false porque el compilador llama al Equals(Object) método .

if myVariable1.Equals myVariable2 then
    printfn "\nStructures 'myVariable1' and 'myVariable2' are equal"
else

  Dim myVariable1 As Int16 = 20
