Extract file from LZH archive

Question

I have LZH archive (.lzh, .lha extensions of archive), and need to extract file from it in .NET Framework 4? Does .NET Framework 4 have some built in toolset for this?

Answer 1

我将 LHA Java 解压缩库移植到 .NET 中，称为LHA Decompressor 。

Answer 2

Thanks very much to the author above. I have posted a simple implementation of it for reference.

            //Extracts all files in the .lzh archive
            LhaFile lhaFile = null;
            byte[] dest = new byte[8];
            List<string> extractedFileList = new List<string>();

            lhaFile = new LhaFile(filePath, Encoding.UTF7);
            IEnumerator<LhaEntry> enumerator = lhaFile.GetEnumerator();

            while (enumerator.MoveNext())
            {
                string fileName = enumerator.Current.GetPath();
                LhaEntry lhaEntry = lhaFile.GetEntry(fileName);
                dest = lhaFile.GetEntryBytes(lhaEntry);

                File.WriteAllBytes(Path.Combine(extractionPath, fileName), dest);

                string fullPath = Path.Combine(extractionPath, fileName);
                extractedFileList.Add(fullPath);

            }

            lhaFile.Close();
