Explanation

The DirectoryInfo class in C# provides information about the contents of a directory. It represents an object that provides access to a directory and its contents.

To use DirectoryInfo, you can create an instance of it by passing the path of the directory as a string to the constructor. The GetFiles() and GetDirectories() methods then return an array of file or folder names respectively.

In this example, we retrieve the contents of the directory "MyDirectory" and print the name of each file and folder inside it.

Use

DirectoryInfo is useful when you need to obtain information about a directory and its contents. It allows you to retrieve the names of files and folders, as well as other information like creation time, modification time, and file size.
