c# - C# NUnrar library (extracting password protected rar files without password)

Question

I am using this library in C# to extract RAR files.

http://nunrar.codeplex.com/

Is it able to extract a file even if it is password protected? It doesn't even ask for password. How is that possible?

I am creating RAR files using WinRar and putting password on them.

我正在解密受密码保护的 rar 存档我的下一个项目，因为我认为我已经完成了（zip 文件模糊了我的记忆）。

正如另一条评论所说，我一直在寻求帮助，但希望我能尽快完成这项工作。

（2018 年底。）使用密码解压 RAR（4 或 5 格式）存档的解决方案：安装 Nuget Packages 7z.Libs ( https://www.nuget.org/packages/7z.Libs/ ) 和 Squid-Box。 SevenZipSharp ( https://www.nuget.org/packages/Squid-Box.SevenZipSharp/ )。使用此代码：（编辑：纠错）

        public void Unpack()
        {
            var rawBytes = File.ReadAllBytes(".\\Some.rar");

            using (var stream = new MemoryStream(rawBytes, true))
            {
                // Toggle between the x86 and x64 bit dll
                var path = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase, Environment.Is64BitProcess ? "x64" : "x86", "7z.dll");
                SevenZip.SevenZipBase.SetLibraryPath(path);

                using (var outMemStream = File.Create(".\\SomeSingleFile.txt"))
                {
                    var extractor = new SevenZipExtractor(stream, "passwordXXX");
                    var entry = extractor.ArchiveFileData.Single(info => false == info.IsDirectory);    
                    extractor.ExtractFile(entry.Index, outMemStream);                        
                }
            }
        }
