如何在 C# 中将字节数组转换为 zip 存档？

Question

我在数据库中有一个 ziparchive 的字节数组。当我从数据库中检索数据并尝试转换回 Ziparchive 时，它会抛出错误。有没有办法从字节数组转换为 zipArchive？

据此answer我认为可以将您的流字节数组转换为 zip 存档：

using (var compressedFileStream = new MemoryStream()) {
    //Create an archive and store the stream in memory.
    using (var zipArchive = new ZipArchive(compressedFileStream, ZipArchiveMode.Update, false)) {
        foreach (var caseAttachmentModel in caseAttachmentModels) {
            //Create a zip entry for each attachment
            var zipEntry = zipArchive.CreateEntry(caseAttachmentModel.Name);

            //Get the stream of the attachment
            using (var originalFileStream = new MemoryStream(caseAttachmentModel.Body)) {
                using (var zipEntryStream = zipEntry.Open()) {
                    //Copy the attachment stream to the zip entry stream
                    originalFileStream.CopyTo(zipEntryStream);
                }
            }
        }

    }

    return new FileContentResult(compressedFileStream.ToArray(), "application/zip") { FileDownloadName = "Filename.zip" };
}

在这里，使用 new FileContentResult(compressedFileStream.ToArray(), "application/zip") { FileDownloadName = "Filename.zip" }; 行，如果您已经转换为 zip 文件，那么您可以像这样将流字节数组转换为 zip 存档：

new FileContentResult(your_stream_byte_array, "application/zip") { FileDownloadName = "Filename.zip" };
