If entryNameEncoding is set to null, entry names are decoded according to the following rules: For entries where the language encoding flag is set, the entry names are decoded by using UTF-8.For entry names where the language encoding flag (in the general-purpose bit flag of the local file header) is not set, the entry names are decoded by using the specified encoding.If entryNameEncoding is set to a value other than null, entry names are decoded according to the following rules: Each extracted file has the same relative path to the directory specified by destinationDirectoryName as its source entry has to the root of the archive. Otherwise, if an error occurs during extraction, the archive remains partially extracted. Exceptions related to validating the paths in the destinationDirectoryName or sourceArchiveFileName parameters are thrown before extraction. This method creates the specified directory and all subdirectories, if necessary. Each extracted file has the same relative path to the directory specified by destinationDirectoryName as its source entry has to the root of the archive.Īn archive entry was compressed by using a compression method that is not supported. The destination directory cannot already exist. This method creates the specified directory and all subdirectories. ZipFile.ExtractToDirectory(zipPath, extractPath)

String startPath = zipPath = extractPath = zipPath) To use the ZipFile class, you must reference the System.IO.Compression.FileSystem assembly in your project. It compresses the contents of a folder into a zip archive and extracts that content to a new folder. This example shows how to create and extract a zip archive by using the ZipFile class. The archive specified by sourceArchiveFileName is not a valid zip archive.Īn archive entry was not found or was corrupt.Īn archive entry was compressed by using a compression method that is not supported.
