Brilliant. Thank you. It would 8 hrs for me to find this post, but it was well worth the wait.

when I use it, iT says
The type or namespace name 'ConfigurationManager' does not exist in the namespace 'System.Configuration' (are you missing an assembly reference?)

do you know why?

you have to add a reference to System.Configuration
