Represents a compressed file within a zip archive.
Assembly: System.IO.Compression (in System.IO.Compression.dll)
Thetype exposes the following members.
|Archive||Gets the zip archive that the entry belongs to.|
|CompressedLength||Gets the compressed size of the entry in the zip archive.|
|FullName||Gets the relative path of the entry in the zip archive.|
|LastWriteTime||Gets or sets the last time the entry in the zip archive was changed.|
|Length||Gets the uncompressed size of the entry in the zip archive.|
|Name||Gets the file name of the entry in the zip archive.|
|Delete||Deletes the entry from the zip archive.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|Open||Opens the entry from the zip archive.|
|ToString||Retrieves the relative path of the entry in the zip archive. (Overrides Object::ToString().)|
|ExtractToFile(String)||Overloaded. Extracts an entry in the zip archive to a file. (Defined by ZipFileExtensions.)|
|ExtractToFile(String, Boolean)||Overloaded. Extracts an entry in the zip archive to a file, and optionally overwrites an existing file that has the same name. (Defined by ZipFileExtensions.)|
A zip archive contains an entry for each compressed file. The class enables you to examine the properties of an entry, and open or delete the entry. When you open an entry, you can modify the compressed file by writing to the stream for that compressed file. You open an entry by calling the Open method.
If you reference the System.IO.Compression.FileSystem assembly in your project, you can access two extension methods for the class. Those methods are ExtractToFile(ZipArchiveEntry, String) and ExtractToFile(ZipArchiveEntry, String, Boolean), and they enable you to decompress the contents of the entry to a file. The System.IO.Compression.FileSystem assembly is not available in Windows 8. In Windows Store apps, you can decompress the contents of an archive by using DeflateStream or GZipStream, or you can use the Windows Runtime types Compressor and Decompressor to compress and decompress files.
You can retrieve an entry either by iterating through the Entries collection in ZipArchive, or by calling the GetEntry method in ZipArchive. You can create a new entry by calling CreateEntry or CreateEntryFromFile.
The first example shows how to create a new entry in a zip archive and write to it.
The second example shows how to use the ExtractToFile(ZipArchiveEntry, String) extension method. You must reference the System.IO.Compression.FileSystem assembly in your project for the code to execute.
