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)
压缩类
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
解压缩
public static class UnZipClass
{
public static void UnZip(string[] args)
{
ZipInputStream s = new ZipInputStream(File.OpenRead(args[0]));
ZipEntry theEntry;
while ((theEntry = s.GetNextEntry()) != null)
{
string directoryName = Path.GetDirectoryName(args[1]);
string fileName = Path.GetFileName(theEntry.Name);
//生成解压目录
Directory.CreateDirectory(directoryName);
if (fileName != String.Empty)
{
//解压文件到指定的目录
FileStream streamWriter = File.Create(args[1] + theEntry.Name);
int size = 2048;
byte[] data = new byte[2048];
while (true)
{
size = s.Read(data, 0, data.Length);
if (size > 0)
{
streamWriter.Write(data, 0, size);
}
else
{
break;
}
}
streamWriter.Close();
}
}
s.Close();
File.Delete(args[0]);
}
}
关于参数的说明:UnZip的参数是string[],第一个参数是压缩文件路径,第二个是压缩文件夹路径!
