File & Directory Operations

For working with Files we need to import the System.IO namespace

File and FileInfo Class

Provides methods for creating, copying, moving, deleting and editing files.
FileInfo provides Instance methods while File provides static methods
When a lot of operations need to be performed the recommendation is to use FileInfo class.
A permission check is performed by C# for security reasons this is only performed once when using the Instance Method

Directory and DirectoryInfo Class

Similar to File and FileInfo but used for working with directories

Path Class

Provides methods that allow us to work with string that contains information about a file path or directory path

Info

• The using statement in C# is similar to the “with” Context Manager in Python
• It is used to call the Dispose() method explicitly which when a resource is not needed anymore
