- The following example defines two color-related enumerations, `SingleHue` and `MultiHue`. The latter has the `FlagsAttribute` attribute; the former does not. The example shows the difference in behavior when a range of integers, including integers that do not represent underlying values of the enumeration type, are cast to the enumeration type and their string representations displayed.   For example, note that 3 cannot be represented as a `SingleHue` value because 3 is not the underlying value of any `SingleHue` member, whereas the `FlagsAttribute` attribute makes it possible to represent 3 as a `MultiHue` value of `Black, Red`.

+ The following example defines another enumeration with the `FlagsAttribute` attribute and shows how to use bitwise logical and equality operators to determine whether one or more bit fields are set in an enumeration value. You can also use the <xref:System.Enum.HasFlag%2A?displayProperty=nameWithType> method to do that, but that is not shown in this example.
