Question

我在数据库中有一个ziparchive字节数组。当我从数据库中检索数据并尝试转换回Ziparchive时，它会抛出一个错误。有没有办法从字节数组转换为zipArchive？

从此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，使用行new FileContentResult(compressedFileStream.ToArray(), "application/zip") { FileDownloadName = "Filename.zip" };，如果您已经转换为zip文件，那么您可以将您的流字节数组转换为zip存档，如下所示：

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

如何在c＃中将字节数组转换为zip存档？
