PowerTCP Zip Compression for .NET

PowerTCP Zip Compression for .NET features

 

PowerTCP Zip Compression for .NET Archive Component

Use Dart's Archive component within the .NET Framework to compress, decompress, and encrypt files and streams.

The Archive component provides both high-level ease of use for those developers who just want to write code as quickly as possible, and low-level power for those developers who require finer control. Features include:

• Quickly compress a single file (or multiple files using wildcards...including recursive directory trees) with a single line of code.
• Quickly decompress files with only a single line of code.
• Compress to or from files or streams.
• Customize the level of compression (high, medium, or low) based on your speed and size requirements.
• Encrypt the output data using standard zip encryption.
• Create a self-extracting zip file.
• Supports spanning.
• Manipulate the files in the archive on a global level (i.e. unzip all files at once, assign a comment to all files at once, etc) or on a file level (i.e. unzip a single file contained in the archive, assign the comment on a single file in the archive, etc).
• C#, VB.NET, ASP.NET, and Delphi .NET sample projects included.
• Integrates with Visual Studio 2005, 2008, 2010, 2012
• .NET Framework 4 Client Profile compatible

 

Interface

 

Public Constructors
Archive	Overloaded. Initialize a new instance of the Archive class.
Public Properties
Comment	Gets or sets the comment for the entire collection.
CompressionLevel	Gets or sets the compression level for data compression.
ContainsListCollection	Gets a value indicating whether the collection is a collection of IList objects.
Count	Gets the number of ArchiveItem objects within the Archive.
DefaultCompressionMethod	Gets or sets the default compression algorithm used for data compression.
DefaultEncryption	Gets or sets the encryption algorithm used for the the entire collection.
ExcludePattern	Gets or sets the files to exclude when using wildcards.
Format	Gets the file format used for the archive file.
IncludeSubs	Gets or sets whether subdirectories are included when using wildcards.
IsSynchronized	Gets a value indicating whether access to the ICollection is synchronized (thread-safe).
Item	Gets or sets the object at the specified index.
Overwrite	Gets or sets a value which determines how files are overwritten when decompressing files.
Password	Gets or sets the encryption password for the entire archive.
PreservePath	Gets or sets a value which determines if file paths are preserved when creating a compressed archive.
ProgressSize	Gets or sets the frequency to raise the Progress event.
SelfExtractConfiguration	Gets or sets a SelfExtractConfiguration object, which is used to define the specification of a self-extraction operation.
SpanConfiguration	Gets or sets a SpanConfiguration object, which is used to span or split an archive over several volumes.
SyncRoot	Gets an object that can be used to synchronize access to the Archive.
Tag	Gets or sets an object reference that can be used to associate this instance with any other.
TempFileDirectory	Gets or sets a value inidicating the directory to store any temp files created during compression operations.
VolumeLabel	Gets or sets the volume label
Public Methods
Abort	Abort the current operation
Add	Add a file or multiple files to the archive.
BeginQuickUnzip	Asynchronously load a compressed stream and unzip in one step.
BeginQuickZip	Asynchronously add a file or files and zip in one step.
BeginUnzip	Asynchronously decompress the items in the current collection to the specified directory
BeginZip	Asynchronously compress the items in the current collection and generate a zip archive that is written to a Stream.
Clear	Removes all elements from the ArrayList.
CopyTo	Copies the entire ArrayList to a compatible one-dimensional Array, starting at the specified index of the target array.
GetEnumerator	Returns an enumerator for the collection.
GetList	Returns an IList that can be bound to a data source from an object that does not implement an IList itself.
Insert	Insert one or more files into the collection starting from the specified index.
Open	Opens a compressed file and populates the Archive collection to reflect the items in the compressed file.
QuickUnzip	Open a compressed file archive and uncompress in one step.
QuickZip	Add a file or files and compress in one step where the destination is a Stream.
RemoveAt	Removes the element at the specified index of the collection.
RemoveRange	Removes a range of elements from the ArrayList.
Reset	Remove the elements in the collection and reset all of the properties of the collection to their defaults.
Unzip	Decompress the items in the current collection to the specified directory
Zip	Compress the items in the current collection and generate a zip archive to the destination stream
Public Events
BusyChanged	This event is raised when the Busy property in the Archive component gets changed.
Disk	This event is raised when a new removable media volume is needed during a spanning process.
EndUnzip	This event is raised when an asynchronous Unzip operation completes
EndZip	This event is raised when an asynchronous zip operation completes
Exception	This event is raised when an Exception condition occurs during an Archive-level operation.
Progress	This event is raised periodically to indicate the progress of the current compression or decompression activity.
SpanProgress	This event is raised periodically to indicate the progress of a spanning operation.
