我想使用FastZip提取RAR文件,这是我的代码:
FastZip fastZip = new FastZip();
fastZip.CreateEmptyDirectories = true;
if (password != "")
{
fastZip.Password = password;
}
string fileFilter = null;
fastZip.ExtractZip(CompressedFilePathValue, OutputFolderPathValue, fileFilter);
但是我总是会出错:
cannot find central directory
RAR文件正常,我可以使用WinRAR正确打开它,因此如何使用带有FastZip或不带FastZip的Sharpziplib提取RAR文件?注意:我不想使用SharpCompress,因为我不支持密码。有什么方法可以使用sharpziplib提取RAR文件?感谢您的帮助
[SevenZipSharp支持rar存档和密码。
这里是如何提取RAR文件,没有错误,找不到中央目录:
using (Stream fs = File.OpenRead(CompressedFilePathValue))
using (var zf = new ZipFile(fs))
{
if (!String.IsNullOrEmpty(password))
{
// AES encrypted entries are handled automatically
zf.Password = password;
}
foreach (ZipEntry zipEntry in zf)
{
if (!zipEntry.IsFile)
{
// Ignore directories
continue;
}
String entryFileName = zipEntry.Name;
// to remove the folder from the entry:
//entryFileName = Path.GetFileName(entryFileName);
// Optionally match entrynames against a selection list here
// to skip as desired.
// The unpacked length is available in the zipEntry.Size property.
// Manipulate the output filename here as desired.
var fullZipToPath = Path.Combine(OutputFolderPathValue, entryFileName);
var directoryName = Path.GetDirectoryName(fullZipToPath);
if (directoryName.Length > 0)
{
Directory.CreateDirectory(directoryName);
}
// 4K is optimum
var buffer = new byte[4096];
// Unzip file in buffered chunks. This is just as fast as unpacking
// to a buffer the full size of the file, but does not waste memory.
// The "using" will close the stream even if an exception occurs.
using (var zipStream = zf.GetInputStream(zipEntry))
using (Stream fsOutput = File.Create(fullZipToPath))
{
StreamUtils.Copy(zipStream, fsOutput, buffer);
}
}
}
老实说,此功能仅适用于使用sharpziplib创建的rar文件,不会打开使用winrar创建的rar
