value = instance.WriteItemData(itemData, buffer, offset, count)

public long WriteItemData( 
   Stream itemData,

   int offset,
   int count
)

Parameters

itemData

A System.IO.Stream object.

buffer

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

offset

The zero-based byte offset in buffer at which to begin copying bytes read from itemData.

count

The number of bytes to be copied to buffer in each loop iteration.

Return Value

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

The specified stream must support reading. It is not necessary for the stream to support seeking or writing. The specified stream is read to using the specified buffer until the end of the itemData is reached.

The method does not close specified stream.
