在記憶體中編寫 Zip 檔案

以下示例將返回包含提供給它的檔案的壓縮檔案的 byte[] 資料，而無需訪問檔案系統。

public static byte[] ZipFiles(Dictionary<string, byte[]> files)
{
    using (MemoryStream ms = new MemoryStream())
    {
        using (ZipArchive archive = new ZipArchive(ms, ZipArchiveMode.Update))
        {
            foreach (var file in files)
            {
                ZipArchiveEntry orderEntry = archive.CreateEntry(file.Key); //create a file with this name
                using (BinaryWriter writer = new BinaryWriter(orderEntry.Open()))
                {
                    writer.Write(file.Value); //write the binary data
                }
            }
        }
        //ZipArchive must be disposed before the MemoryStream has data
        return ms.ToArray();
    }
}
