Open a CSV file

[Stefke]

Hi,

I've exported our Exchange 5.5 server info into a CSV file. I know want to
create a VB.Net application which reads the CSV file and then process the
information in it.

Can anyone tell me what I should do to create the application. The file is
called info.csv.
And I want to process it row by row.

Kind Regards

Stefke

Hi Stefke,

dim SR as New StreamReader("c:\My Documents\info.csv")
dim txtLine as String
dim Strings as String()
txtLine = SR.ReadLine()
Strings()=String.Split(",",txtLine)

da.Fill(ds, "TextFile")

MessageBox.Show(ex.ToString)

I hope this helps a little bit?

It should be noted that whilst this would "normally" work, it will fail if
the data contacts a comma ... eg

"hello","this has a comma, see!!",100

You would need to parse the string looking for opening and closing quotation
marks and taking commas between them as part of the data and not a
delimiter.

Herfried and Cor's suggestion for using the text connection string would do
this for you...

Simon

The benchmarks of processing csv files using the microsoft drivers are
not very good.
