[vb]
Module Module1 
 
    Enum days

        monday = 1 
        yuesday = 2 
        wednesday = 3 
        thursday = 4 
        friday = 5 
        saturday = 6 
    End Enum 
 
    Sub Main() 
        Dim showday As days 
        showday = days.thursday 
        Dim myday As String 
        Console.WriteLine("枚举days") 
        For Each myday In [Enum].GetNames(GetType(days)) 
            Console.Write("{0} ", myday) 
        Next 
        Console.ReadLine() 
        Dim i As Integer 
        For Each i In [Enum].GetValues(GetType(days)) 
            Console.WriteLine("一周中的第{0}天是{1}", i, [Enum].GetName(GetType(days), i)) 
        Next 
        Console.ReadLine() 
    End Sub 
 
End Module
