本文實(shí)例為大家分享了C#實(shí)現(xiàn)文件的壓縮與解壓的具體代碼，供大家參考，具體內(nèi)容如下

需引入 System.IO.Compression;

1.C#代碼（入門案例）

Console.WriteLine("壓縮文件...............");      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("壓縮完成。");      Console.WriteLine("解壓文件...............");      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("解壓完成。");Console.ReadKey();

C#,GZipStream,文件,壓縮,解壓
