本文将告诉大家一个在 ZipArchive 里追加文件夹,以及添加过滤文件处理的压缩文件辅助方法
实现的方法的代码如下
/// <summary> /// 追加文件夹到压缩文件里面 /// </summary> /// <param name="archive"></param> /// <param name="sourceDirectoryName"></param> /// <param name="zipRelativePath">在压缩包里面的相对路径</param> /// <param name="compressionLevel"></param> /// <param name="fileCanAddedPredicate"></param> public static void AppendDirectoryToZipArchive(ZipArchive archive, string sourceDirectoryName, string zipRelativePath, CompressionLevel compressionLevel = CompressionLevel.Fastest, Predicate<string>? fileCanAddedPredicate = null) { var folders = new Stack<string>(); folders.Push(sourceDirectoryName); while (folders.Count > 0) { var currentFolder = folders.Pop(); foreach (var item in Directory.EnumerateFiles(currentFolder)) { if (fileCanAddedPredicate != null && !fileCanAddedPredicate(item)) { continue; } archive.CreateEntryFromFile(item, Path.Join(zipRelativePath, Path.GetRelativePath(sourceDirectoryName, item)), compressionLevel); } foreach (var item in Directory.EnumerateDirectories(currentFolder)) { folders.Push(item); } } }
演示的调用的代码如下
var zipFile = "1.zip"; using (var fileStream = new FileStream(zipFile, FileMode.Create, FileAccess.Write)) { using var zipArchive = new ZipArchive(fileStream, ZipArchiveMode.Create, leaveOpen: true/*自己释放 FileStream 对象*/, Encoding.UTF8); Foo.AppendDirectoryToZipArchive(zipArchive, @"C:lindexiLibrary", "Lib"); Foo.AppendDirectoryToZipArchive(zipArchive, @"C:lindexiCA", "Pem", fileCanAddedPredicate: filePath => { var fileName = Path.GetFileName(filePath); return fileName != "foo.ignore.file"; }); }
支持设置文件夹加入之后在安装包的什么相对路径下,也支持过滤文件
如果加入到安装包的根路径下,只需要让 zipRelativePath 参数传入空字符串即可,如下面代码
Foo.AppendDirectoryToZipArchive(zipArchive, @"C:lindexiLibrary", "");
全部的代码如下
using System.IO.Compression; using System.Text; var zipFile = "1.zip"; using (var fileStream = new FileStream(zipFile, FileMode.Create, FileAccess.Write)) { using var zipArchive = new ZipArchive(fileStream, ZipArchiveMode.Create, leaveOpen: true/*自己释放 FileStream 对象*/, Encoding.UTF8); Foo.AppendDirectoryToZipArchive(zipArchive, @"C:lindexiLibrary", "Lib"); Foo.AppendDirectoryToZipArchive(zipArchive, @"C:lindexiCA", "Pem", fileCanAddedPredicate: filePath => { var fileName = Path.GetFileName(filePath); return fileName != "foo.ignore.file"; }); } class Foo { /// <summary> /// 追加文件夹到压缩文件里面 /// </summary> /// <param name="archive"></param> /// <param name="sourceDirectoryName"></param> /// <param name="zipRelativePath">在压缩包里面的相对路径</param> /// <param name="compressionLevel"></param> /// <param name="fileCanAddedPredicate"></param> public static void AppendDirectoryToZipArchive(ZipArchive archive, string sourceDirectoryName, string zipRelativePath, CompressionLevel compressionLevel = CompressionLevel.Fastest, Predicate<string>? fileCanAddedPredicate = null) { var folders = new Stack<string>(); folders.Push(sourceDirectoryName); while (folders.Count > 0) { var currentFolder = folders.Pop(); foreach (var item in Directory.EnumerateFiles(currentFolder)) { if (fileCanAddedPredicate != null && !fileCanAddedPredicate(item)) { continue; } archive.CreateEntryFromFile(item, Path.Join(zipRelativePath, Path.GetRelativePath(sourceDirectoryName, item)), compressionLevel); } foreach (var item in Directory.EnumerateDirectories(currentFolder)) { folders.Push(item); } } } }
以上的 C:lindexiLibrary
等文件夹是我的用于测试的文件夹,还请大家换成自己的文件夹
本文代码放在 github 和 gitee 上,可以使用如下命令行拉取代码
先创建一个空文件夹,接着使用命令行 cd 命令进入此空文件夹,在命令行里面输入以下代码,即可获取到本文的代码
git init git remote add origin https://gitee.com/lindexi/lindexi_gd.git git pull origin 76bed002b4da4f363037c2d39f41596be1c2b177
以上使用的是 gitee 的源,如果 gitee 不能访问,请替换为 github 的源。请在命令行继续输入以下代码,将 gitee 源换成 github 源进行拉取代码
git remote remove origin git remote add origin https://github.com/lindexi/lindexi_gd.git git pull origin 76bed002b4da4f363037c2d39f41596be1c2b177
获取代码之后,进入 LebenehainaiJelearlowiwaw 文件夹,即可获取到源代码
