Hi @selrac , You may also use the Matches activity which is used for Regex operations.

[image] aksh1yadav: as per my view better to use always to call full namespace so you will not need to import it I beg to differ - always fully qualifying makes code a lot harder to write and read. There’s very little benefit to not importing a namespace (unless you’re microoptimizing memory…

[image] andrzej.kniola: I beg to differ You are already a unique champion :wink: pal @andrzej.kniola [image] andrzej.kniola: always fully qualifying makes code a lot harder to write and read Agree but Namespace imports are simply time savers / readability enhancements for the source…

I found how to resolve the error by adding the full library path system.Text.RegularExpressions.Regex.IsMatch like:

system.Text.RegularExpressions.Regex.IsMatch(DateTaskAttrib, “(JAN|FEB|MAR|APR|MAY|JUN|JUL|AUG|SEP|OCT|NOV|DEC)-\d{2}”)

Hope helps someone else
