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(UInt64) sobrecargas del método. Si se define una conversión implícita entre el obj argumento y y UInt64 el argumento no se escribe como , Objectlos compiladores realizan una conversión implícita y llaman al Equals(UInt64) método . De lo contrario, llaman al Equals(Object) método , que siempre devuelve false si su obj argumento no es un UInt64 valor. En el ejemplo siguiente se muestra la diferencia de comportamiento entre las dos sobrecargas del método. En el caso de los Bytevalores , UInt16y UInt32 , la primera comparación devuelve true porque el compilador realiza automáticamente una conversión de ampliación y llama al Equals(UInt64) método , mientras que la segunda comparación devuelve false porque el compilador llama al Equals(Object) método .

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.
