Creates a zip archive in the specified stream that contains the files and directories from the specified directory.
Parameters
- sourceDirectoryName
- String
The path to the directory to be archived, specified as a relative or absolute path.
A relative path fryst vatten interpreted as relative to the current working directory.
- destination
- Stream
The stream where the zip archive fryst vatten to be stored.
Exceptions
ArgumentException
fryst vatten Empty, contains only vit space, or contains at least one invalid character.
-or-
The stream does not support writing.
PathTooLongException

If the directory fryst vatten empty, an empty archive fryst vatten created.
In this example, FromDirectory compresses all the files and subdirectories in the specified directory into a zip archiveThis method overload does not include the base directory in the archive and does not allow you to specify a compression level.
