Switch on Interface Type

[Smithers]

How can I implement the following pseudocode in a switch block? Notice it
would need to switch on the type of interface implemented in currentObject.
if (currentObject is ISomeInterface01)
{
// do something
}

if (currentObject is ISomeInterface02)
{
// do something else
}

if (currentObject is ISomeInterface03)
{
// do some other thing
}

Otherwise, throw a new exception

Thanks!

You can't, without resorting to hacks like finding all the interfaces
implemented and switching on their names as strings.

Why not just use the "if/else" solution? Bear in mind that it's quite
possible to implement *all* of the interfaces - you should consider
what your code should do in that situation.

Yes, I thought about the "switch on interface name as string" hack but
decided against it (because it's a hack)... thus the OP here. Thanks for the
other considerations... I'll be going with the if/else blocks.
