Bonnie,

When you get your answer please let me know what it is...
I suspect that with only a couple hundred records you'll find that there isn't "much" of a difference either way...
So the most flexible would probably be the filter...(that's just a guess)

With more records (Over 1,000), I suspect the select would be "significantly" faster (based on my experience in Visual FoxPro).

I have a DataTable that could have a lot of Rows in it (ok, maybe not thousands, but at least it's possible to have a couple hundred). Anyway, I have a particular row that I'm searching for, based on a key column. I'm trying to determine the fastest, most efficient way to find that row.

I've not used #2 at all yet, but it seems fairly straightforward. Again, I don't know what to expect in terms of overhead.
