And you are unlucky, in your place, internet do not allow you to read language documentation ?

fileName=String.Concat(fileName, "info.Numero");

Please explain which syntax you used that did not yield proper results.

C#

fileName=String.Concat(fileName, "info.Numero");

Imagine the filename is "file.txt", your way would lead to the filename "file.txtinfo.Numero".
Here you want the value of the Numero property of the info variable. You passed a string instead. You should not put that between double quotes.
Moreover, files often have extensions. You may want to add the number after the name only, not after the extension.
A more suitable way may be

C#

fileName = string.format
(
   "{0}{1}{2}",
   Path.GetFileNameWithoutExtension(fileName),
   info.Numero,
   Path.GetExtension(fileName)
);

With this method, you would get "file1.txt" instead.
