Comentários

O valor das constantes nos DayOfWeek intervalos de enumeração de DayOfWeek.Sunday a DayOfWeek.Saturday . Se for cast em um inteiro, seu valor varia de zero (o que indica DayOfWeek.Sunday ) a seis (o que indica DayOfWeek.Saturday ).

A DayOfWeek propriedade retorna uma constante enumerada; ela não reflete as configurações regionais e de idioma de um sistema. Para recuperar uma cadeia de caracteres que representa um nome de dia da semana localizado para uma determinada data, chame uma das sobrecargas do método que inclui um parâmetro e passe-o para as cadeias de ToString format ddd caracteres de formato personalizado dddd ou . Para obter detalhes, consulte Como extrair o dia da semana de uma data específica.
