C#使用GZipStream实现文件的压缩与解压

本文实例为大家分享了C#实现文件的压缩与解压的具体代码，供大家参考，具体内容如下

需引入 System.IO.Compression;

1.C#代码（入门案例）

Console.WriteLine("压缩文件...............");
      using (FileStream fr = File.OpenRead("d:\test.txt"))
      {
 using (FileStream fw = File.OpenWrite("d:\test.zip"))
 {
   using (GZipStream gz = new GZipStream(fw, CompressionMode.Compress))
   {

     byte[] by = new byte[1024 * 1024];
     int r = fr.Read(by, 0, by.Length);
     while (r > 0)
     {
gz.Write(by, 0, r);
r = fr.Read(by, 0, r);
     }
   }
 }
      }
      Console.WriteLine("压缩完成。");


      Console.WriteLine("解压文件...............");
      using (FileStream fr = File.OpenRead("d:\test.zip"))
      {
 using (GZipStream gz = new GZipStream(fr, CompressionMode.Decompress))
 {
   using (FileStream fw = File.OpenWrite("d:\test2.txt"))
   {

     byte[] by = new byte[1024 * 1024];
     int r = gz.Read(by, 0, by.Length);
     while (r > 0)
     {
fw.Write(by, 0, r);
r = gz.Read(by, 0, r);
     }
   }
 }
      }

Console.WriteLine("解压完成。");
Console.ReadKey();
