c＃wpf，属性的绑定值取决于布尔值

Question

Sorry for my bad english. I want to bind a BorderBrush of ListBoxItem depending on the bool value of object. I have a Directory class, that has IsForCopy and IsCutted bool props. So, if IsForCopy is true, then BorderBrush = Red, if IsCutted is true, then BorderBrush = Blue. How can I do this?

ListBox.ItemContainerStyle>
                <Style TargetType="{x:Type ListBoxItem}" BasedOn="{StaticResource {x:Type ListBoxItem}}">
                    <EventSetter Event="MouseDoubleClick" Handler="SecondListBoxItem_MouseDoubleClick"/>
                    <Setter Property="BorderBrush" Value="What do I should type there?"></Setter>
                </Style>
            </ListBox.ItemContainerStyle>

You need a class that implements IValueConverter. Then in the convert method you can specify how you want to map a bool to a brush any way you want. And every binding has a converter attribute which you can set to this class that implemented IValueConverter.
