WPF多枚枚举标志转换器参数？

Question

如果枚举值为(A | B | C),我需要一个可见的控件.

我知道如何使用转换器将控件的可见性绑定到SINGLE枚举(A).

在这种情况下,我该如何做同样的事情呢？参数会怎么样？

这是我使用的转换器:

public class EnumToVisibilityConverter : IValueConverter {
    public object Convert( object value, Type targetType, object parameter, System.Globalization.CultureInfo culture ) {
        if ( value == null || parameter == null || !( value is Enum ) )
            return Visibility.Hidden;
        string State = value.ToString( );
        string parameterString = parameter.ToString( );

        foreach ( string state in parameterString.Split( ',' ) ) {
            if ( State.Equals( state ) )
                return Visibility.Visible;
        }
        return Visibility.Hidden;
    }

    public object ConvertBack( object value, Type targetType, object parameter, System.Globalization.CultureInfo culture ) {
        throw new NotImplementedException( );
    }
}

这是XAML绑定:

<UserControl.Visibility>
    <Binding
        Path="GameMode" Source="{x:Static S:Settings.Default}" Converter="{StaticResource ETVC}"
        ConverterParameter="{x:Static E:GameMode.AudiencePoll}" Mode="OneWay"/>
</UserControl.Visibility>

如何将(A | B | C)传递给转换器参数？它就像说的一样简单{x:Static E:Enum.A | E:Enum.B | E:Enum.C}吗？

我能在这里找到答案

为了节省每个人的旅行

<Binding Path="PathGoesHere" Source="{x:Static SourceGoesHere}" Converter="{StaticResource ConverterKeyGoesHere}">
    <Binding.ConverterParameter>
        <EnumTypeGoesHere>A,B,C</EnumTypeGoesHere>
    </Binding.ConverterParameter>
</Binding>
