Detect duplicate entries in datatable rows
Posted on 2008-10-20
I have a datatable with the following columns:
givenname, surname, title, dept, identifier
Now I have thousands of rows like this for each user in the company:

Now I want to detect these users and write the identifier (as this is unique) of these users to a list(of string).
How can I do that?
