将N个txt文档压缩到zip包里面-优快云博客

本文介绍了一个使用C#实现的文件压缩和解压功能。该方法首先获取当前目录，并从中筛选出特定类型的文件进行压缩，同时提供了解压功能。压缩过程中可以指定输出目录及压缩后的文件名。

protected static string path()
        {
            string str3 = Directory.GetCurrentDirectory();
            string[] sArr = str3.Split('b');
            return sArr[0] + "zip\\";
        }

        public SetZip()
        {
            //删除目标文件夹下的所有txt文件
            DeleteFile(path());
        }

        public static void DeleteFile(string dirRoot)
        {
            try
            {
                string[] rootDirs = Directory.GetDirectories(dirRoot); //当前目录的子目录：
                string[] rootFiles = Directory.GetFiles(dirRoot);        //当前目录下的文件：

                foreach (string s2 in rootFiles)
                {
                    File.Delete(s2);                      //删除文件
                }
                foreach (string s1 in rootDirs)
                {
                    DeleteFile(s1);
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message.ToString());
            }
        }
        /// <summary>
        /// 将原文件的压缩到指定目录下并命名为指定文件名
        /// </summary>
        /// <param name="sourceFiles">源文件的存储地址集合</param>
        /// <param name="zipFolderPath">压缩文件的输出目录</param>

        public void GetZipFromFiles(List<string> sourceFiles, string zipFolderPath, string zipFileName)
        {
            zipFolderPath = zipFolderPath + @"/" + zipFileName + ".zip";
            FileStream ZipFileStream = File.Create(zipFolderPath);
            ZipOutputStream ZipOutStream = new ZipOutputStream(ZipFileStream);
            sourceFiles.ForEach(e =>
            {
                FileStream myFileStream = File.OpenRead(e);
                byte[] ByteBuffer = new byte[myFileStream.Length];
                myFileStream.Read(ByteBuffer, 0, ByteBuffer.Length);
                myFileStream.Close();
                ZipEntry ZipFileEntry = new ZipEntry(Path.GetFileName(e));
                ZipOutStream.PutNextEntry(ZipFileEntry);
                ZipOutStream.SetLevel(6);
                ZipOutStream.Write(ByteBuffer, 0, ByteBuffer.Length);
            });
            ZipOutStream.Finish();
            ZipOutStream.Close();
