You can use File.WriteAllLines:

string[] mystrings = new string[] { "Foo", "Bar", "Baz", "Qux" };

System.IO.File.WriteAllLines("myfile.txt", mystrings);

If you wish to append the text lines to the file, use AppendAllText:

string appendText = "This is extra text" + Environment.NewLine;
File.AppendAllText(path, appendText);

Use the StreamWriter class; take a look at this tutorial. A new line is simply the character \n (Unix) or the characters \r\n (Windows).
