231,210 PointsThe System and System.IO namespaces have different contents.
The System namespace contains fundamental classes and base classes that define commonly-used value and reference data types, events and event handlers, interfaces, attributes, and processing exceptions. This would include classes such as Array, Buffer, Console, Convert, Math, Object, Random, and String. Each class provides a number of useful methods.
The System.IO namespace contains types that allow reading and writing to files and data streams, and types that provide basic file and directory support. This includes classes such as Directory, DirectoryInfo, File, FileInfo, FileStream, Stream, StreamReader, and StreamWriter. Each of these classes provide their own set of useful methods.
