Poniżej przedstawiam prosty program w konsoli (można go rozbudować czy też dorobić do niego GUI) do parsowania e-maili
napisany w języku C#

Projekt w VS2008 Express Edition (download)

Jak użyjesz kodu w swoim programie to napisz. Tak z ciekawości chciałbym wiedzieć 🙂

Proszę o komentarze i uwagi 🙂
