.NET Core(C#)使用SharpCompress压缩解压文件(.rar,.zip,tar.bz2,.7z,.tar.gz)

一、SharpCompress 库简介

 .NET Core中使用SharpCompress库可以方便地进行多种格式的文件压缩和解压缩操作，支持的格式包括.rar, .zip, .tar.bz2, .7z, .tar.gz 等。

SharpCompress是一个开源的.NET库，提供了对多种压缩格式的读写支持。

本文主要介绍.NET Core(C#)使用sharpcompress压缩文件(.zip,.tar.bz2,.tar.gz)的代码以解压(.rar,.zip,.7z)的代码。

二、使用案例

 

    /// <summary>
    /// 文件压缩解压缩处理
    /// </summary>
    public class CompressHelper
    {
        public static string RootPath
        {
            get
            {
                return FreeSpireHelper.RootPath;
            }
        }
        public static string CompressPath
        {
            get
            {
                string path = FreeSpireHelper.RootPath + "/comprestemp/";
                if (Directory.Exists(path) == false)
                    Directory.CreateDirectory(path);
                return path;
            }
        }

        #region Rar
        /// <summary>
        /// 解压缩rar文件---目前不支持rar压缩
        /// </summary>
        /// <param name="file"></param>
        #endregion


        #region Zip
        /// <summary>
        /// 压缩zip文件，指定文件夹，全部压缩
        /// </summary>
        /// <param name="path"></param>
        public static void CompressZip(string path)
        {
            DirectoryInfo dir = new DirectoryInfo(path);
            string filename = path  + ".zip";
            using (var zip = File.OpenWrite(filename))
            using (var zipWriter = WriterFactory.Open(zip, ArchiveType
            .Zip, CompressionType.Deflate))
            {
                zipWriter.WriteAll(path, "*", SearchOption.AllDirectories);
            }
        }
        #endregion


        #region 7z
        /// <summary>
        /// 7z解压缩----目前不支持7z压缩
        /// </summary>
        /// <param name="filename"></param>
        #endregion


        #region 通用方法
        /// <summary>
        /// 通用解压 rar，zi，7z，tar等
        /// </summary>
        /// <param name="filename"></param>
        public static List<string> DeCompress(string filename)
        {
            List<string> result = new List<string>();

            filename = RootPath + filename;
            FileInfo file = new FileInfo(filename);
            if (file.Exists == false)
                throw new Exception("压缩文件不存在");
            var archive = ArchiveFactory.Open(filename);
            foreach (var entry in archive.Entries)
            {
                if (!entry.IsDirectory)
                {
                    //Console.WriteLine(entry.Key);
                    string path = CompressPath + file.Name.Substring(0, file.Name.LastIndexOf("."));
                    if (Directory.Exists(path) == false)
                        Directory.CreateDirectory(path);
                    entry.WriteToDirectory(path, new
                    ExtractionOptions()
                    {
                        ExtractFullPath = true,
                        Overwrite = true
                    });

                    result.Add((path+ "/"+ entry.Key).Replace(RootPath, ""));
                }
            }

            return result;
        }
        #endregion
    }

测试代码：

//文件压缩解压
//List<string> result=CompressHelper.DeCompress("5.zip");
////CompressHelper.DeCompress("2.7z");
////List<string> result=CompressHelper.DeCompress("3.tar");
////List<string> result = CompressHelper.DeCompress("202504.rar");

//foreach (string s in result) {
//    Console.WriteLine( s);
//}


CompressHelper.CompressZip("G:\\QLTest\\Core_Solution\\Dotnet8\\PDFTest\\PDFTest\\bin\\Debug\\net8.0\\comprestemp\\202504");
