Create ZIP

ZIP is a file compression and archiving format used to reduce file sizes for efficient storage and transmission. It combines multiple files and directories into a single archive, often named with a '.zip' extension. ZIP archives are widely used for data backup, software distribution, and file sharing.

To create a ZIP file in C#, use the using statement to instantiate a ZipArchive object from the System.IO.Compression namespace. Inside the using block, invoke the CreateEntryFromFile method to add files to the ZIP file. The file path can specify a directory or file that you want to add to the ZIP archive. Finally, output the ZIP file using the ZipArchive functionality.
