Sequential File Access
Using System.IO is the recommended way to create text files, but should you need to use older text file-creation methods, this section shows you how.
Sequential access works best when you want to process files consisting only of text, such as files created with a typical text editor, not files in which data is divided into a series of records. Sequential access is not well suited for storing long series of numbers, because each number is stored as a character string. Thus, a four-digit number would require four bytes of storage instead of the two bytes required to store the same number as an integer.
