I must create an application consul who acquires me from rows .csv file only the data that are found in column 1 and those of column 4. To the data of column 1 in its turn it goes added to it ...1@example.com. To insert the acquired data in database..il a language of programming that I use is the c #. has advised to me to use foreach. thanks for the answers

It's hard to tell what you are asking. If you are new to C# you might want to start with a good book like "Beginning Microsoft Visual C# 2008" or "Beginning C# 3.0: An Introduction to Object Oriented Programming" both from Wrox. Also you might try http://www.google.com/search?hl=en&q=C%23+Tutorials for a tutorial on C#.

If you can ask a more specific question people here will generally be glad to help.

Ti spiego meglio quello che devo fare: devo creare un programma console dato una tabella .csv contenente 4 colonne e 5000 righe contenenti dei contatti..io devo prendere da questa tabella tramite c#sola la prima colonna e che rappresenta l'username e la quarta colonna che rappresenta la password per poi inviarli a un dato database..prima di inviare questi dati al database però io devo aggiungere a tutti i dati della colonna 1 ovvero gli username la dicitura ..@alice.it e poi procedere all'invio.. te ne sarei molto grato visto ke mi trovo in alto mare e nn so dove mettere le mani...grazie ancora x l'aiuto..ciao

This is an international forum, and AFAIK, most people here understand English but not Italian.... ;)

Well it's a long time since I spoke Italian with any confidence but:
***********************************
I'll try to explain what I'm attempting: I need a console application that reads a CSV having 4 columns and 5000 rows, the first column is the username, the fourth the password. I need to add the email suffix @alice.it to the username and send the details to a database using C#. I find myself adrift on the high seas [may have misconstrued that] and appreciate your help, thanks etc.

*********************************************
Okay so I would attempt this in the following stages:

• Read the file using TextReader and StreamReader: http://www.csharp-station.com/HowTo/...eTextFile.aspx
• use String.Split to get an array representing the columns
  
• Add the suffix to the first column
• Pass the data to the database, you can use a stored procedure or SQL but you'll have to give more information. Is it a new table, an existing one etc?

Credo che il metodo preferito sarebbe quello di utilizzare un ciclo while piuttosto
che foreach.
