Solution 3

You create a new file every time, try using this form[^] and append your data each time round. You should also consider using more meaningful field names in your code as the ones in your sample above will give you nightmares in the future maintenance of your code.

Go and look at the link I posted, you need to open your file with "append = true", to ensure that each line of data gets added to the end of the file, rather than overwriting the existing information, thus:
TextWriter tw = new StreamWriter(path, true);
