) As Long

'Usage
 
Dim instance As ZipReader

Dim stream As Stream

Dim buffer() As Byte

Dim value As Long

 

value = instance.ReadItemData(stream, buffer)

public long ReadItemData( 

   Stream stream,

   byte[] buffer

)

Parameters

stream

A System.IO.Stream object that will receive the item's data.

buffer

An array of System.Byte to be used as the buffer in the data copy loop from ZipReader to stream.

Return Value

This method allows you to supply your own buffer for the loop that drives the copy operation from ZipReader to the specified System.IO.Stream. It prevents ZipReader from allocating a temporary buffer to perform copy loop.

The specified stream must support writing. It is not necessary for the stream to support seeking or reading. The specified stream is written to using the specified buffer until the end of the item's data is reached.

The method uses the buffer from offset zero up to the upper bound of the array.

The method does not close specified stream.

An interesting use of this method is to use the System.IO.Steam.Null stream object. This will effectively skip an item's data and move ZipReader to the next item.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
