What is the best way to remove duplicates from a datatable?

Question

I have checked the whole site and googled on the net but was unable to find a simple solution to this problem.

I have a datatable which has about 20 columns and 10K

If you have access to Linq I think you should be able to use the built in group functionality on the in memory collection and pick out the duplicate rows

Search Google for Linq Group by for examples
