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();
