// Display the SwitchLevelAttribute for the BooleanSwitch.
Object[] attribs = typeof(BooleanSwitch).GetCustomAttributes(typeof(SwitchLevelAttribute), false);
if (attribs.Length == 0)
    Console.WriteLine("Error, couldn't find SwitchLevelAttribute on BooleanSwitch.");
else
    Console.WriteLine(((SwitchLevelAttribute)attribs[0]).SwitchLevelType.ToString());

' Display the SwitchLevelAttribute for the BooleanSwitch.
Dim attribs As [Object]() = GetType(BooleanSwitch).GetCustomAttributes(GetType(SwitchLevelAttribute), False)
If attribs.Length = 0 Then
    Console.WriteLine("Error, couldn't find SwitchLevelAttribute on BooleanSwitch.")
Else
    Console.WriteLine(CType(attribs(0), SwitchLevelAttribute).SwitchLevelType.ToString())
End If
