本文提供了一个使用C#实现的简单压缩与解压缩类，利用.NET Framework的DeflateStream进行流压缩与解压操作。

using System;
using System.Collections.Generic;
using System.Text;

namespace Compression
{
   public class DeflateCompression : ICompression
   {

   public DeflateCompression()
   {
   }

   #region ICompression 成员

   public void Compress(System.IO.Stream orgStream, System.IO.Stream cmpStream)
   {
   System.IO.Compression.DeflateStream zipStream = new System.IO.Compression.DeflateStream(cmpStream, System.IO.Compression.CompressionMode.Compress);

   byte[] buffer = new byte[1024 * 10];
   int offset = 0;
   while (true)
   {
   int bytesRead = orgStream.Read(buffer, offset, 1024 * 10);
   if (bytesRead == 0)
   {
   break;
   }
   zipStream.Write(buffer, 0, bytesRead);
   }
   }

   public void DeCompress(System.IO.Stream cmpStream, System.IO.Stream orgStream)
   {
   System.IO.Compression.DeflateStream zipStream = new System.IO.Compression.DeflateStream(cmpStream, System.IO.Compression.CompressionMode.Decompress);

   byte[] buffer = new byte[1024 * 10];
   int offset = 0;
   while (true)
   {
   int bytesRead = zipStream.Read(buffer, offset, 1024 * 10);
   if (bytesRead == 0)
   {
   break;
   }
   orgStream.Write(buffer, 0, bytesRead);
   }
   }

   #endregion
   }
}
