在C#中创建可保留文件夹结构的压缩归档文件

using System.IO.Compression;

string zipPath = "archive.zip";
using (ZipArchive archive = ZipFile.Open(zipPath, ZipArchiveMode.Create))
{
    // 添加文件夹和文件到ZIP文件中
}

string folderPath = "path/to/folder";
string[] files = Directory.GetFiles(folderPath, "*", SearchOption.AllDirectories);

foreach (string file in files)
{
    string entryName = file.Substring(folderPath.Length + 1); // 获取相对路径
    ZipArchiveEntry entry = archive.CreateEntry(entryName);

    using (FileStream fileStream = new FileStream(file, FileMode.Open))
    using (Stream entryStream = entry.Open())
    {
        fileStream.CopyTo(entryStream);
    }
}
