C#压缩与解压库及函数（zip格式，需要参数：压缩文件夹）

我使用的是SharpZipLib的压缩解压库，链接我就不提供了，下载引用就好了

关于压缩，啥也不说，直接先来代码（我的代码基本你可以直接拿去用，我都写成静态函数不用实例化）

public static class ZipClass     {         public static void ZipFileMain(string[] args)         {             string[] filenames = Directory.GetFiles(args[0]);               Crc32 crc = new Crc32();             ZipOutputStream s = new ZipOutputStream(File.Create(args[1]));               s.SetLevel(6); // 0 - store only to 9 - means best compression               foreach (string file in filenames)             {                 //打开压缩文件                 FileStream fs = File.OpenRead(file);                 byte[] buffer = new byte[fs.Length];                 fs.Read(buffer, 0, buffer.Length);                 ZipEntry entry = new ZipEntry(Path.GetFileName(file));                   entry.DateTime = DateTime.Now;                   // set Size and the crc, because the information                 // about the size and crc should be stored in the header                 // if it is not set it is automatically written in the footer.                 // (in this case size == crc == -1 in the header)                 // Some ZIP programs have problems with zip files that don't store                 // the size and crc in the header.                 entry.Size = fs.Length;                 fs.Close();                   crc.Reset();                 crc.Update(buffer);                   entry.Crc = crc.Value;                   s.PutNextEntry(entry);                   s.Write(buffer, 0, buffer.Length);               }               s.Finish();             s.Close();             Directory.Delete(args[0], true);         }     }

　　关于参数的说明：ZipFileMain的参数是string[],第一个参数是压缩文件夹路径，第二个是压缩文件路径
