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();

2. 运行结果
