The File, FileInfo, Directory, and DirectoryInfo classes are considered utility classes. They normally work with stream objects, allowing you to manipulate files and directory structures.

FileInfo and DirectoryInfo classes expose only static data members.

The ____ class has implementations for Write( ) and WriteLine( ) methods similar to the Console class methods.

The StreamReader class extends the ____ class.
