DataTable loading a SqlDataReader (dt.Load())?
Vanilla DataTable using SqlDataAdapter
or SqlDataReader ?
or is there a better way using Generics? If so, how? Essentially I
want to get about 50-100 rows of data (2 columns) out of my database
and use this is serveral places without caching it as the data could
get updated several times during a period of 5 minutes and thus, needs
to be always up-to-date.
TIA

a native forward only/read only sql data reader should give you the best
performance.

DataReader is certainly the "fastest" way to get the data, but you also have
to consider what you are doing with it. If you are holding on to the data
over a period of time with only a DataReader to firehose over, you are
holding a connection open.
Loading into a DataTable may add a couple of milliseconds to the operation
but you can close the connection and allow it to return to the pool, and now
you have your data in a disconnected manner until the next time you need to
get it.
In the big scheme of things, with only 50 to 100 rows, we are talking mere
miliseconds here.

Thought it might be - but there's no harm in asking. Most of my work
involves DataTables anyway.
Thanks.

Hi,
If I have a lot of integers and want do something with each digit as
integer, what is the fastest way to get there?
Eg. Make 12345 into an iterable object, like or "12345"
(Btw: What is the English term for this process; itemize? tokenize?
digitize? sequence?)
Some examples:

I don't want to load the entire file into physical memory, memory-mapped files

Hi Everyone,
I am trying to write a program that does a few things very fast
and with efficient use of memory...
a) I need to parse a space-delimited file that is really large,
upwards fo a million lines.
b) I need to store the contents into a unique hash.
c) I need to then sort the data on a specific field.
d) I need to pull out certain fields and report them to the user.

What is the fastest way to search a client-side database?
I have about 60-65 kb of data downloaded to the client which is

alphabetic order. These names may have accented and umlauted
characters (which are present as the plain ASCII - not as the entity
