C#使用GZipStream实现文件的压缩与解压

这篇文章主要为大家详细介绍了C#使用GZipStream实现文件的压缩与解压，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

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();
