PKZip.ZipReader.Constructor

Method Signatures

 Sub Constructor(ZipData As MemoryBlock, Force As Boolean = False)
 Sub Constructor(ZipStream As BinaryStream, Force As Boolean = False)
 Sub Constructor(ZipStream As FolderItem, Force As Boolean = False)

Parameters

`Constructor(MemoryBlock, Boolean)`

Name	Type	Comment
ZipData	MemoryBlock	The zip archive to read from.
Force	Boolean	Optional. If `True`, then the archive is forcibly read.

`Constructor(BinaryStream, Boolean)`

Name	Type	Comment
ZipStream	BinaryStream	The zip archive to read from.
Force	Boolean	Optional. If `True`, then the archive is forcibly read.

`Constructor(FolderItem, Boolean)`

Name	Type	Comment
ZipStream	FolderItem	The zip archive to read from.
Force	Boolean	Optional. If `True`, then the archive is forcibly read.

Remarks

Opens the archive for reading.

If Force=True then less strict techniques are used:

The zip data is assumed to start at offset 0
The central directory is ignored
Invalid entries are skipped by scanning forward until the next entry is found (slow)
Checksum mismatches will not cause MoveNext() to return False (LastError is updated correctly, though)

Forcible reading can yield a performance boost on well-formed archives.
