If you want to save a String array to a file then call IO.File.WriteAllLines.
If you want to read a file into a String array then call IO.File.ReadAllLines.
If you want to save the contents of a RichTextBox to a file then call RichTextBox.SaveFile.
If you want to read a file into a RichTextBox then call RichTextBox.LoadFile.
