dotnet C# 简单的追加文件夹到 ZipArchive 压缩文件的方法
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:\lindexi\Library\", "Lib");
Foo.AppendDirectoryToZipArchive(zipArchive, @"C:\lindexi\CA\", "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:\lindexi\Library\", "");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:\lindexi\Library\", "Lib");
Foo.AppendDirectoryToZipArchive(zipArchive, @"C:\lindexi\CA\", "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:\lindexi\Library 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
