本文將告訴大家一個在 ZipArchive 裡追加資料夾,以及新增過濾檔案處理的壓縮檔案輔助方法
實現的方法的程式碼如下
/// <summary>
/// 追加資料夾到壓縮檔案裡面
/// </summary>
/// <param name="archive"></param>
/// <param name="sourceDirectoryName"></param>
/// <param name="zipRelativePath">在壓縮包裡面的相對路徑</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);
}
}
}
演示的呼叫的程式碼如下
var zipFile = "1.zip";
using (var fileStream = new FileStream(zipFile, FileMode.Create, FileAccess.Write))
{
using var zipArchive = new ZipArchive(fileStream, ZipArchiveMode.Create, leaveOpen: true/*自己釋放 FileStream 物件*/, 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";
});
}
支援設定資料夾加入之後在安裝包的什麼相對路徑下,也支援過濾檔案
如果加入到安裝包的根路徑下,只需要讓 zipRelativePath 引數傳入空字串即可,如下面程式碼
Foo.AppendDirectoryToZipArchive(zipArchive, @"C:\lindexi\Library\", "");
全部的程式碼如下
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/*自己釋放 FileStream 物件*/, 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>
/// 追加資料夾到壓縮檔案裡面
/// </summary>
/// <param name="archive"></param>
/// <param name="sourceDirectoryName"></param>
/// <param name="zipRelativePath">在壓縮包裡面的相對路徑</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
等資料夾是我的用於測試的資料夾,還請大家換成自己的資料夾
本文程式碼放在 github 和 gitee 上,可以使用如下命令列拉取程式碼
先建立一個空資料夾,接著使用命令列 cd 命令進入此空資料夾,在命令列裡面輸入以下程式碼,即可獲取到本文的程式碼
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 不能訪問,請替換為 github 的源。請在命令列繼續輸入以下程式碼,將 gitee 源換成 github 源進行拉取程式碼
git remote remove origin
git remote add origin https://github.com/lindexi/lindexi_gd.git
git pull origin 76bed002b4da4f363037c2d39f41596be1c2b177
獲取程式碼之後,進入 LebenehainaiJelearlowiwaw 資料夾,即可獲取到原始碼
