Row count was created by Gennaro
Hi!
i was wandering if is it possible:

- to count the total number of rows of a text file on the read side
and then
- to use the result (total number) as output to a filed on the write side

any suggestions?

thanks in advance

Hi Genaro,

Yes, it is! If you want to add the line count to each row you have to use the power of the .NET Heater and the following little script. In the attachment you’ll find an example.
Code:
int rows = -1; public object DoWork() { // only read the input file one time if (rows < 0) { // Getting the READ Adapter TextFileAdapter adapter = (TextFileAdapter)AdapterRead; // Read all lines string [] lines = File.ReadAllLines(adapter.Filename); // adopt the line count rows = lines.Length; } return rows; }

If you want to add the line count to a Header/Footer row you can find an example here. Processing of CSV header and footer rows
