Files & Directories

In VB.Net you can read and write from a text stream using the StreamReader or StreamWriter objects.
There are also BinaryReader and BinaryWriter objects for binary data.
The StreamReader and StreamWriter objects work either with a filename string or a FileStream object.
The FileStream class provides random access to a disk file and allows you to specify whether you want to create or open a file.

Scripting.Dictionary
