I can add a line of text to a file written on a sd card.
I managed to create (name hello.txt) and write 3 lines, but if I want to add another one without rewriting the first three as I do?
thanks for the help
StreamWriter textFile = new StreamWriter(rootDirectory + @ "\hello.txt"); textFile.WriteLine("Hello SD card"); textFile.WriteLine("Hello M."); textFile.WriteLine("3 riga!!!!!!!!!!"); textFile.Close();
