Generating text files

[Guest]

Do you have to generate a huge file?

If you don't have to generate a big number of rows an elegant solution could
be to use XSL (you can have the input in XML and apply your XSL template to
export to your given format):

About XSL solution:

XSL Tutorial:

The strong point of this solution is that if you need any change in the
future on the style of the output you will have only to modify this XSL.

On the other hand if you have to manage with a lot of rows better go
manually with a loop, and write the ouput into an stream.

Hi, I have to do a LayOut text files, to send to a financial institute...

Each line has defined columns, example position 1 lenght 2 - string content
/ position 3 - date content (ddmmaaaa)... numeric contents (15,2), etc

Do you know the best form doing that? any examples? components?

Thanks

If you use a Dataset you will get the XML format for free, then you can
create an XSL template.

If I where in your shoes, I would make a simple proof of concept version
using XSL + XML Datasets and check if the response times are good.

No, it´s not a big file, I hope maximum 1 or 2 MegaByte... I have to loop
some tables and build the strings to make the file...

Take a look at an excellent library called FileHelpers -- perfect for
this kind of thing
