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
