In your code you should always make sure, that the user entered something
valid.

If you cannot do that fully, then you should keep care of the possible
errors. (In your example, it is the cast to the FTP Request.)

It is always a good idea to make the application as "fool proven" as
possible (e.g. giving an error message: "You did not enter a valid FTP
Url." instead of an application crash!)

With kind regards,
