File Access with Visual Basic Run-Time Functions

Visual Studio .NET 2003

In earlier versions of Visual Basic, files were processed using the Open statement and other related statements and functions. Visual Basic .NET includes compatible functions as part of its library, specifically in the System.IO.File namespace (for details, see System.IO Namespace). The topics in this section show how to process files directly to create, manipulate, and store text and other data using available file I/O functions.
