Overview

The System.IO.Directory class is a fundamental class in .NET that provides access to the directory structure of a file system. It allows you to create, read, write, and manipulate files and directories within a specified area of the file system.

It's commonly used for tasks like: reading directory contents, creating new files, and managing file hierarchy structures.

You can use it to easily interact with file system operations through a convenient and predictable API.

Key Methods

Here are some essential methods:

• `GetDirectoryContents(type)`: Returns a directory object.
• `GetFiles(type)`: Returns a list of files.
• `GetDirectories(type)`: Returns a list of directory objects.
• `CreateDirectory(path)`: Creates a new directory at the given path.
• `DeleteDirectory(path)`: Deletes the directory specified by the path.
• `CopyDirectory(sourcePath, destinationPath)`: Copies the contents of the source directory to the destination directory.

Example: Creating a Directory

Let's create a directory called 'my_directory' and then add a file inside it.

First, we'll call `CreateDirectory('my_directory')`.

Then, we'll use `GetDirectoryContents(type)` to get the directory object.

Finally, we'll add a file with a name and content to the directory.

Example: Reading a Directory

Let's get the contents of the directory.

Using `GetDirectoryContents(type)` again, we can retrieve the directory's contents.

Then, we can read and print each file in the directory.
