ZipArchive.CreateFromDirectory Method (String, String, CompressionLevel, Boolean)

Creates a Zip archive at the path destinationArchive that contains the files and directories in the directory specified by sourceDirectoryName. The directory structure is preserved in the archive, and a recursive search is performed for files to be archived. The archive must not exist. If the directory is empty, an empty archive will be created.

If a file in the directory cannot be added to the archive, the archive will be left incomplete and invalid and the method will throw an exception. This method optionally includes the base directory in the archive.

If an error is encountered when adding files to the archive, this method will stop adding files and leave the archive in an invalid state. The paths are permitted to specify relative or absolute path information. Relative path information is interpreted as relative to the current working directory. If a file in the archive has data in the last write time field that is not a valid Zip timestamp, an indicator value of 1980 January 1 at midnight will be used for the file's last modified time.

public static void CreateFromDirectory(
	string sourceDirectoryName,
	string destinationArchiveFileName,
	CompressionLevel compressionLevel,
	bool includeBaseDirectory


Type: System.String

The path of the directory on the file system to be archived.

Type: System.String

The name of the archive to be created.

Type: Microsoft.TeamFoundation.Framework.Server.CompressionLevel

The level of the compression (speed/memory vs. compressed size trade-off).

Type: System.Boolean

True to indicate that a directory named sourceDirectoryName should be included at the root of the archive. False to indicate that the files and directories in sourceDirectoryName should be included directly in the archive.


sourceDirectoryName or destinationArchive is a zero-length string, or it contains only white space, or it contains one or more invalid characters as defined by InvalidPathChars.


sourceDirectoryName or destinationArchive is null.


In sourceDirectoryName or destinationArchive, the specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters.


The path specified in sourceDirectoryName or destinationArchive is invalid, (for example, it is on an unmapped drive), or the directory specified by sourceDirectoryName does not exist.


destinationArchive exists, or an I/O error occurred while you are opening a file to be archived.


destinationArchive specified a directory, or the caller does not have the required permission.


sourceDirectoryName or destinationArchive is in an invalid format.
