There is a great port of the JAVA compression package to .NET. Check out
http://www.icsharpcode.net/OpenSource/SharpZipLib/.
Using the .NET port the uncompression is comething like:
private static byte[] Inflate(byte[] bytes)
{
MemoryStream mis = new MemoryStream();
mis.Write(bytes, 0, bytes.Length);
mis.Flush();
mis.Position = 0;
Stream ins = new GZipInputStream(mis);
MemoryStream mos = new MemoryStream();
byte[] buf = new byte[102400];
while (true)
{
int count = ins.Read(buf, 0, buf.Length);
if (count == 0)
break;
mos.Write(buf, 0, count);
}
ins.Close();
mos.Position = 0;
byte[] uncompressedBytes = new byte[mos.Length];
mos.Read(uncompressedBytes, 0,
uncompressedBytes.Length);
mos.Close();
return uncompressedBytes;
}
In the case of the bond trading sysetm that I am working on compression is
required only from the server (java) to client (.NET). I am sure that
compression code in .NET is pretty straightforward as well.
