So I've been searching for method to replcace on particular line in an UTF-8 (easily readable and copy-paste) file.
I found lots of methods that were searching for matches in rows and replacing them.
It was mentioned very often that it's impossible to replace a row in text file using C#, unless they're "accidentally" same size.
Mine will be, it will be a file with constant length 200~300 of on each row, repeating vast amount of times 2000~???.
Could someone please provide me (link with) script that would replace row 12 to for example PLPLPPLPLPL (this test file will be just that short), so I can evaluate the script and modify it to my purposes and most likely learn from it. Problem is, it needs to be able to replace the row regardless what's on it. The length of each and single one row will be exactly same.
