Re: Load a string of CSV from memory into a dataset

Yes there is. As a matter of fact, you should avoid writing to the disk as
that is hella slow.

What you can do however is that the "Stream" you get - (is it
MemoryStream?) - which after decryption and just before writing to the CSV
file - subject that to a "StreamReader" - to get a string out of it.

Great, now that you have a CSV'ed string out of it, split the string for New
lines.
Then run a foreach on the resulting array and split each line (array
element) using the "," character.
For each sub array element - create an object array - and do a
DataTable.LoadDataRow(passinthearray,true).

Thats it. Problem solved.
