DataTabel

[Paddy]

Can one read / write a data tabel from / to a file without extra operations.
If so how is it done? If not, what is the alternative?

Many thanks.

Where is this data table stored? Excel, SQL Server, MySQL, Oracle, Access,
etc?
There are different answers for each one.

If you have a DataSet object in .NET, that you'd like to write to a file:
that would be called "serialization" and you can get a quick intro on this
tiny article:

Hope this helps,

Thank you. So my understanding is that one has to "serialize" - but to do so
is slow, and it would therefore be better to write one's own class. Right?

Hi Paddy,

The article gives advice to not use Datasets over the .NET Remoting because
it usually uses XML serialization to send the data, when binary
serialization is faster. That bit does not apply to your situation.

If you need to read and write objects to a file, easily and reliably, XML
serialization is the way to go.
