C# DeflateStream Write
Description
DeflateStream Write Writes compressed bytes to the underlying
stream from the specified byte array.
Syntax
DeflateStream.Write has the following syntax.
public override void Write(
byte[] array,//from ww w. j a v a2 s .c om
int offset,
int count
)
Parameters
DeflateStream.Write has the following parameters.
array- The buffer that contains the data to compress.offset- The byte offset in array from which the bytes will be read.count- The maximum number of bytes to write.
Returns
DeflateStream.Write method returns
Example
The following example shows how to compress and decompress bytes by using the Read and Write methods.
//from w ww .jav a 2s . c o m
using System;
using System.Text;
using System.IO;
using System.IO.Compression;
class Program
{
static void Main(string[] args)
{
UnicodeEncoding uniEncode = new UnicodeEncoding();
byte[] bytesToCompress = uniEncode.GetBytes("example text to compress and decompress");
Console.WriteLine("starting with: " + uniEncode.GetString(bytesToCompress));
using (FileStream fileToCompress = File.Create("examplefile.gz"))
{
using (DeflateStream compressionStream = new DeflateStream(fileToCompress, CompressionMode.Compress))
{
compressionStream.Write(bytesToCompress, 0, bytesToCompress.Length);
}
}
byte[] decompressedBytes = new byte[bytesToCompress.Length];
using (FileStream fileToDecompress = File.Open("examplefile.gz", FileMode.Open))
{
using (DeflateStream decompressionStream = new DeflateStream(fileToDecompress, CompressionMode.Decompress))
{
decompressionStream.Read(decompressedBytes, 0, bytesToCompress.Length);
}
}
Console.WriteLine("ending with: " + uniEncode.GetString(decompressedBytes));
}
}
The code above generates the following result.
