Unique values from column in DataTable (source = xml)

[Fred]

Hi all,

I have a DataTable that is being filled with data from an xml file. Now
I need to get an array of strings from that DataTable that returns all
the unique values in a certain column (column name would be 'project'
and will at max contain 30 different projects). What would be the best
way to do this? Using a RowFilter and then pass the results into an
array if possible? I'm a bit stuck on how to do this the best way.

Thanks in advance,
Frederik

Fred,

The best way to do this would be to enumerate through all of the rows in
the table, and then get the unique values yourself. The DataTable/DataView
doesn't have anything really which helps in this regards.

Hope this helps.
