Re: Compare Two Datatables



If you really need to optimize you could progress in parallel in two sorted
lists (you'll have the initial sort cost, then you'll basically browse each
list once in parallel to find out the difference).

I would try that only once I'm 100% sure the simpelst approach is not quick
enough...

I have two datatables that I load. One I load from LDAP, the other gets
loaded from Excel. I need to check to see which names are in the LDAP
that are not in the Excel table and vica versa. There are about 300
records in each. Short of a brute force attack on this, does anyone have
an elegant way to list the non-matches in each table?

Thanks.

John
