CkZipEntry

Represents a single file or directory entry within a Chilkat Zip object.

Object Creation

CkZipEntry obj = new CkZipEntry();

Properties

// str is a CkString object (output)
get_Comment( str )

// pStr is a string (input)
put_Comment( pStr )

The comment stored within the Zip for this entry.

// Returns an integer value
get_CompressedLength( )

The size in bytes of this entry's file data when compression is applied

// Returns an integer value
get_CompressionLevel( )

// newVal is an integer (input)
put_CompressionLevel( newVal )

The compression level. 0 = no compression, while 9 = maximum compression. The default is 6.

// Returns an integer value
get_CompressionMethod( )

// newVal is an integer (input)
put_CompressionMethod( newVal )

Set to 0 for no compression, or 8 for the Deflate algorithm. The Deflate algorithm is the default algorithm of the most popular Zip utility programs, such as WinZip

// Returns an integer value
get_EntryID( )

The unique ID assigned by Zip.NET while the object is instantiated in memory.

// Returns an integer value
get_EntryType( )

Indicates the origin of the entry. There are three possible values: (0) an entry in an existing Zip file, (1) a file on disk referenced by Zip.NET and to be added to the Zip, and (2) an entry created directly from data in memory.

// sysTime is a SYSTEMTIME object (output)
get_FileDateTime( sysTime )

// sysTime is a SYSTEMTIME object (input)
put_FileDateTime( sysTime )

The last-modified time of the Zip entry.

// str is a CkString object (output)
get_FileName( str )

// pStr is a string (input)
put_FileName( pStr )

The file name of the Zip entry.

// Returns a boolean value
get_IsDirectory( )

True if the Zip entry is a directory, false if it is a file.

// str is a CkString object (output)
LastErrorHtml( str )

Error information in HTML format for the last method called.

// str is a CkString object (output)
LastErrorText( str )

Error information in plain-text format for the last method called.

// str is a CkString object (output)
LastErrorXml( str )

Error information in XML format for the last method called.

// Returns an integer value
get_UncompressedLength( )

The size in bytes of this entry's file data when uncompressed.

Methods

// bdata is a CkByteData object (input)
// Returns a boolean value
AppendData( bdata )

Appends binary data to the zip entry's file contents.

// sdata is a CkString object (input)
// Returns a boolean value
AppendStringAnsi( sdata )

Appends a ANSI string to the zip entry's file contents.

// bdata is a CkByteData object (output)
// Returns a boolean value
Copy( bdata )

Returns the compressed data as a byte array.

// str is a CkString object (output)
// Returns a boolean value
CopyToBase64( str )

Returns the compressed data as a Base64-encoded string. This data can be re-added to a Zip by calling Zip.AppendBase64.

Returns true for success, false for failure.

// str is a CkString object (output)
// Returns a boolean value
CopyToHex( str )

Returns the compressed data as a hexidecimal encoded string. This data can be re-added to a Zip by calling Zip.AppendHex.

Returns true for success, false for failure.

// dirPath is a string (input)
// Returns a boolean value
Extract( dirPath )

Unzips this entry into the specified base directory. The file is unzipped to the subdirectory according to the relative path stored with the entry in the Zip. Use ExtractInto to unzip into a specific directory regardless of the path information stored in the Zip.

// dirPath is a string (input)
// Returns a boolean value
ExtractInto( dirPath )

Unzip a file into a specific directory

// bdata is a CkByteData object (output)
// Returns a boolean value
Inflate( bdata )

Inflate a file within a Zip directly into memory.

// addCR is a boolean (input)
// str is a CkString object (output)
// Returns a boolean value
InflateToString( addCR, str )

Inflate and return the uncompressed data as a string. Line-endings are modified to include or not include carriage-returns based on KeepCR. If KeepCR = False, then bare linefeeds are returned, otherwise CRLFs are returned.

Returns true for success, false for failure.

// str is a CkString object (output)
// Returns a boolean value
InflateToString2( str )

Unzip a file directly into memory as a string, and leave line-endings unmodified.

Returns true for success, false for failure.

// Returns a CkZipEntry object
NextEntry( )

Return the next entry (file or directory) within the Zip

Returns a null reference on failure

// bdata is a CkByteData object (input)
// Returns a boolean value
ReplaceData( bdata )

Replaces the zip entry's existing contents with new data.

// sdata is a CkString object (input)
// Returns a boolean value
ReplaceStringAnsi( sdata )

Replaces the zip entry's text content with a new ANSI string.

// filename is a string (input)
// Returns a boolean value
SaveLastError( filename )

Saves the last error information to an XML formatted file.

// Returns a string
comment( )

The comment stored within the Zip for this entry.

Returns a null on failure

// Returns a string
copyToBase64( )

Returns the compressed data as a Base64-encoded string. This data can be re-added to a Zip by calling Zip.AppendBase64.

Returns a null on failure

// Returns a string
copyToHex( )

Returns the compressed data as a hexidecimal encoded string. This data can be re-added to a Zip by calling Zip.AppendHex.

Returns a null on failure

// Returns a string
fileName( )

The file name of the Zip entry.

Returns a null on failure

// addCR is a boolean (input)
// Returns a string
inflateToString( addCR )

Inflate and return the uncompressed data as a string. Line-endings are modified to include or not include carriage-returns based on KeepCR. If KeepCR = False, then bare linefeeds are returned, otherwise CRLFs are returned.

Returns a null on failure

// Returns a string
inflateToString2( )

Unzip a file directly into memory as a string, and leave line-endings unmodified.

Returns a null on failure

// Returns a string
lastErrorHtml( )

Error information in HTML format for the last method called.

Returns a null on failure

// Returns a string
lastErrorText( )

Error information in plain-text format for the last method called.

Returns a null on failure

// Returns a string
lastErrorXml( )

Error information in XML format for the last method called.
