'is' operator is giving compile error when used with switch statem

[Raj]

public static void HandleException (ref Exception io_exException,
bool
i_blnPropagateE xception)
{
switch (true)
{
case io_exException is ApplicationHand ledException:
{
if (i_blnPropagate Exception)
{
throw io_exException;
}
break;
}
case io_exException is ApplicationBusi nessException:
{
if (i_blnPropagate Exception)
{
throw io_exException;
}
break;
}
}
}

This function is not compiling coming with error "A constant value is
required". In the function 'ApplicationHan dledException' and
'ApplicationBus inessException' are classes inherited from
System.Applicat ionException.

Can someone please help me what is the reason and what is the way around? If
this is not possible what can be the alternative way?
