Contains method will work

and system.Collections.Generic.Ienumerable(system.core.uielement) has no method named exists

Cheers @smita.mobifly


If you are looking the Exist option for System.Collections.Generic.List then it will be available.
But if you are looking it for System.Collections.Generic.IEnumerable then it will be not available.

Hi @smita.mobifly,

Just make sure that you’ve imported the System.IO namespace.
