我正在开发 wpf 应用程序。我正在使用sharpziplib 来压缩和解压缩文件。我很容易使用以下代码解压缩 .zip 文件
public static void UnZip(string SrcFile, string DstFile, string safeFileName, int bufferSize)
{
//ICSharpCode.SharpZipLib.Zip.UseZip64.Off;
FileStream fileStreamIn = new FileStream(SrcFile, FileMode.Open, FileAccess.Read);
ZipInputStream zipInStream = new ZipInputStream(fileStreamIn);
string rootDirectory = string.Empty;
if (safeFileName.Contains(".zip"))
{
rootDirectory = safeFileName.Replace(".zip", string.Empty);
}
else
{
rootDirectory = safeFileName;
}
Directory.CreateDirectory(App.ApplicationPath + rootDirectory);
while (true)
{
ZipEntry entry = zipInStream.GetNextEntry();
if (entry == null)
break;
if (entry.Name.Contains("/"))
{
string[] folders = entry.Name.Split('/');
string lastElement = folders[folders.Length - 1];
var folderList = new List<string>(folders);
folderList.RemoveAt(folders.Length - 1);
folders = folderList.ToArray();
string folderPath = "";
foreach (string str in folders)
{
folderPath = folderPath + "/" + str;
if (!Directory.Exists(App.ApplicationPath + rootDirectory + "/" + folderPath))
{
Directory.CreateDirectory(App.ApplicationPath + rootDirectory + "/" + folderPath);
}
}
if (!string.IsNullOrEmpty(lastElement))
{
folderPath = folderPath + "/" + lastElement;
WriteToFile(DstFile + rootDirectory + @"\" + folderPath, bufferSize, zipInStream, rootDirectory, entry);
}
}
else
{
WriteToFile(DstFile + rootDirectory + @"\" + entry.Name, bufferSize, zipInStream, rootDirectory, entry);
}
}
zipInStream.Close();
fileStreamIn.Close();
}
private static void WriteToFile(string DstFile, int bufferSize, ZipInputStream zipInStream, string rootDirectory, ZipEntry entry)
{
FileStream fileStreamOut = new FileStream(DstFile, FileMode.OpenOrCreate, FileAccess.Write);
int size;
byte[] buffer = new byte[bufferSize];
do
{
size = zipInStream.Read(buffer, 0, buffer.Length);
fileStreamOut.Write(buffer, 0, size);
} while (size > 0);
fileStreamOut.Close();
}
但是相同的代码不适用于 .bz2 文件。它在线上给出错误
ZipEntry entry = zipInStream.GetNextEntry();
错误是 - 错误的本地标头签名:0x26594131。我应该如何解压缩 .bz2 文件?您能否提供我可以解决上述问题的任何代码或链接?
