sealed class

This class provides the same functionality as Directory , but in a strongly typed, object-oriented manner. An instance of this type represents a single directory. This class extends FileSystemInfo and implements all its methods . In addition, it adds Parent and Root properties to return the parent and root directories, respectively. Similarly, it also supplies GetDirectories( ) and GetFiles( ) , to retrieve its subdirectories and files, as well as GetFileSystemInfos( ) , which returns both the files and subdirectories contained by the current directory. MoveTo( ) allows you to move a directory from one place to another.

Given the similarity between this type and the Directory type, it may not be clear when one should be used in place of the other. The key difference is the Directory class is a collection of static utility functions, whereas a DirectoryInfo object is an actual object, maintaining state and identity in the classic style of all objects. (In fact, the DirectoryInfo methods often map over to use the corresponding Directory methods.)
