There are a lot of different ways to read and write files (text files, not binary) in C#.
I just need something that is easy and uses the least amount of c
Or, if you are really about lines:
System.IO.File also contains a static method WriteAllLines, so you could do:
IList myLines = new List() { "line1", "line2", "line3", }; File.WriteAllLines("./foo", myLines);
