将文件添加到现有Zip中

我可以成功地将zip文件夹中的文件解压缩到一个文件夹中，但我不太清楚如何获取这些文件并将它们添加到现有的zip文件中。 我将它们提取到桌面上名为“mod”的目录中，然后我需要将它们添加到另一个zip文件中。 救命？ 这是我的提取代码 –

ZipFile zip = ZipFile.Read(myZip); zip.ExtractAll(outputDirectory,ExtractExistingFileAction.OverwriteSilently); 

感谢您的帮助，谢谢。

尝试尝试一下，一旦从源zip文件中提取文件，您需要将目标zip文件读入ZipFile对象，然后可以使用AddFiles方法将源文件添加到目标文件，然后保存。

 using System; using System.Collections.Generic; using System.Linq; using System.Text; using Ionic.Zip; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { string myZip = @"C:\temp\test.zip"; string myOtherZip = @"C:\temp\anotherZip.zip"; string outputDirectory = @"C:\ZipTest"; using (ZipFile zip = ZipFile.Read(myZip)) { zip.ExtractAll(outputDirectory, ExtractExistingFileAction.OverwriteSilently); } using (ZipFile zipDest = ZipFile.Read(myOtherZip)) { //zipDest.AddFiles(System.IO.Directory.EnumerateFiles(outputDirectory)); //This will add them as a directory zipDest.AddFiles((System.IO.Directory.EnumerateFiles(outputDirectory)),false,""); //This will add the files to the root zipDest.Save(); } } } }

将目录添加到ZipFile的修改方法（ 这将适用于单个子目录级别 ）

 using (ZipFile zipDest = ZipFile.Read(myOtherZip)) { foreach (var dir in System.IO.Directory.GetDirectories(outputDirectory)) { zipDest.AddFiles((System.IO.Directory.EnumerateFiles(dir)),false,outputDirectory ); //directory to the root } zipDest.AddFiles((System.IO.Directory.EnumerateFiles(outputDirectory)),false,""); //This will add the files to the root zipDest.Save(); } 

---

从Zip目录中删除文件的方法

 List files = zipDest.EntryFileNames.ToList(); // Get List of all the archives files for (int i = 0; i < files.Count; i++) { if(files[i].Contains("ZipTest")) //replace the directory you wish to delete files from here zipDest.RemoveEntry(files[i]); }

尝试创建一个新的zip：

 using (ZipFile zip = new ZipFile()) { zip.AddFile("1.txt"); zip.AddFile("favicon.png"); zip.AddFile("ElectricityMagnetism.pdf"); zip.Save("BlahBlah.zip"); } 

要将文件添加到zip，请尝试：

 string[] filePaths = new String[] { ... } // Your file paths foreach (string path in filePaths) zip.AddFile(path); zip.Save("..."); // ZIP path

7-Zip有一个可以使用的命令行可执行文件。

 public static void AddFileToZip(string zipPath, string filePath) { if (!File.Exists(zipPath)) throw new FileNotFoundException("Zip was not found.", zipPath); if (!File.Exists(filePath)) throw new FileNotFoundException("File was not found.", filePath); // Create the commandline arguments. string argument = "a -tzip \"" + zipPath + "\" \"" + zipPath + "\""; // Run the 7-Zip command line executable with the commandline arguments. System.Diagnostics.Process process = System.Diagnostics.Process.Start("7za.exe", argument); process.WaitForExit(); }

使用ionic.zip，C＃递归函数路径上的所有目录

 static private void CompressDirRecursive(string path, ref Ionic.Zip.ZipFile dzip) { dzip.AddFiles((System.IO.Directory.GetFiles(path)), false, path); // ROOT foreach (string dir in System.IO.Directory.GetDirectories(path)) { CompressDirRecursive(dir, ref dzip);// NEXT DIRECTORY } } static private void MyTestFunction() { Ionic.Zip.ZipFile dzip = new Ionic.Zip.ZipFile(); System.IO.MemoryStream msOut = new System.IO.MemoryStream(); CompressDirRecursive("ruta que quieras", ref dzip); try { dzip.Save(outputStream: msOut); } catch (Exception ex) { throw ex; } dzip.Dispose(); // etc }
