DataTable.Select Method

I have a DataTable that has 240000 rows in it. My DataTable.Select Method
for a particular filter gets me 840 out of 240000 rows. However, it takes
about 5 seconds to process. The DataTable has 6 columns. The datatype for
the columns are number(10), number(10), varchar2(2000), number(10),
number(10), number(10). \

How can I index (data values are not unique) the in-memory DataTable? How
can I speed up the filter process?

Thanks,
Chris
 
That sounds about right for that many rows. You really
shouldn't load 240,000 rows into a single datatable
and then try to use the datatable like a full fledged database
to run queries against.

Think of all the memory you are taking up. Even if
your app only has one user at a time, this is still a lot.

You need to rerun your query and filter the resultset
down using the actual database.
