Keyoti RapidSpell Desktop .NET

Read and decompress data from the source stream.

Declaration Syntax

Visual Basic

Visual C++

public override int Read(
	byte[] buffer,
	int offset,
	int count
)

public override int Read(
	byte[] buffer,
	int offset,
	int count
)

Public Overrides Function Read ( 
	buffer As Byte(),
	offset As Integer,
	count As Integer
) As Integer

Public Overrides Function Read ( 
	buffer As Byte(),
	offset As Integer,
	count As Integer
) As Integer

public:
virtual int Read(
	array<unsigned char>^ buffer, 
	int offset, 
	int count
) override

abstract Read : 
        buffer : byte[] * 
        offset : int * 
        count : int -> int 
override Read : 
        buffer : byte[] * 
        offset : int * 
        count : int -> int

abstract Read : 
        buffer : byte[] * 
        offset : int * 
        count : int -> int 
override Read : 
        buffer : byte[] * 
        offset : int * 
        count : int -> int

Parameters

buffer (array<Byte>[]()[][]): The buffer into which the decompressed data should be placed.

offset (Int32): the offset within that data array to put the first byte read.

count (Int32): the number of bytes to read.

Return Value

Int32
the number of bytes actually read

Remarks

With a GZipStream, decompression is done through reading.

Examples

	Copy
byte[] working = new byte[WORKING_BUFFER_SIZE]; using (System.IO.Stream input = System.IO.File.OpenRead(_CompressedFile)) { using (Stream decompressor= new Keyoti.RapidSpell.Compression.GZipStream(input, CompressionMode.Decompress, true)) { using (var output = System.IO.File.Create(_DecompressedFile)) { int n; while ((n= decompressor.Read(working, 0, working.Length)) !=0) { output.Write(working, 0, n); } } } }

Copy

byte[] working = new byte[WORKING_BUFFER_SIZE];
using (System.IO.Stream input = System.IO.File.OpenRead(_CompressedFile))
{
    using (Stream decompressor= new Keyoti.RapidSpell.Compression.GZipStream(input, CompressionMode.Decompress, true))
    {
        using (var output = System.IO.File.Create(_DecompressedFile))
        {
            int n;
            while ((n= decompressor.Read(working, 0, working.Length)) !=0)
            {
                output.Write(working, 0, n);
            }
        }
    }
}
