C# 解压程序内嵌的压缩包类型资源文件

首先引入SevenZipBase 和 7z.dll

public R7z()
            {
                var path = Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, "7z\\7z.dll");
                SevenZipBase.SetLibraryPath(path);
            }
            
我们看到SevenZipBase 中的构造方法有四个
传入文件路径的带密码的和不带密码的、传入Stream的带密码的和不带密码的

public SevenZipExtractor(Stream archiveStream);
    public SevenZipExtractor(string archiveFullName);
    public SevenZipExtractor(string archiveFullName, string password);
    public SevenZipExtractor(Stream archiveStream, string password);
    
我们的资源文件读取都是byte[] ,转换成Stream调用对应构造方法即可

static void Main(string[] args)
        { @"C:\Users\Administrator\Desktop\2a2baf80-8ded-4a09-80d4-880a740ebb49");
            new R7z().Decompression(BytesToStream(Resources.资源文件), @"C:\Users\35337\Desktop\123456");

Console.WriteLine("完毕");
            Console.ReadLine();
        }
        
        public static Stream BytesToStream(byte[] bytes)
        {
            Stream stream = new MemoryStream(bytes);
            return stream;
        }

        /// 解压文件
        /// </summary>
        /// <param name="CompressFile">压缩的文件</param>
        /// <param name="targetAddress">解压的目标地址下</param>

        public bool Decompression(Stream archiveStream, string targetAddress, string password = "")
        {
            try
            {
                if (string.IsNullOrWhiteSpace(password))
                {
                    using (var tmp = new SevenZipExtractor(archiveStream))
                    {
                        for (int i = 0; i < tmp.ArchiveFileData.Count; i++)
                        {
                            tmp.ExtractFiles(targetAddress, tmp.ArchiveFileData[i].Index);
                        }
                    }
                }
                else
                {
                    using (var tmp = new SevenZipExtractor(archiveStream, password))
                    {
                        for (int i = 0; i < tmp.ArchiveFileData.Count; i++)
                        {
                            tmp.ExtractFiles(targetAddress, tmp.ArchiveFileData[i].Index);
                        }
                    }
                }
            }
            catch (Exception ex)
            { }
            return false;
        }
