Ok, I know that
Paul knew this, but did anyone else notice that the
VB.NET Try...Catch syntax includes a 'when' clause?
Try
[ tryStatements ]
[ Catch [ exception [ As type ] ] [ When expression ]
[ catchStatements ] ]
[ Exit Try ]
...
[ Finally
[ finallyStatements ] ]
End Try
When
Optional. A Catch statement with a When clause will only catch exceptions when expression evaluates to True. A When clause is only applied after checking the type of the exception, and expression may refer to the identifier representing the exception.
I never did! I can't think of a good use for it right at this moment, but I'm still shocked that I never noticed it before... now what to do with it?
