Error while downloading pdf template from azure blob storage

I am getting an error while downloading a pdf template from azure blob storage, i intend to use this template to fill data and process further in my code without saving in local, and finally upload it back to azure blob.

Error reads as : "Unexpected token 'endobj' in PDF stream. The file may be corrupted. If you think this is a bug in PDFSharp, please send us your PDF file."



below is my code:



BlobClient blobClient = _ClientGet.GetBlobClient(pathAndFileName);

if (await blobClient.ExistsAsync())
{
BlobDownloadInfo download = await blobClient.DownloadAsync();

if (download.ContentLength > 0)
{
byte[] pdfBytes = new byte[download.ContentLength];
await download.Content.ReadAsync(pdfBytes, 0, (int)download.ContentLength);

using (MemoryStream pdfStream = new MemoryStream(pdfBytes))
{
PdfDocument pdfDocument = PdfReader.Open(pdfStream, PdfDocumentOpenMode.Import);
return pdfDocument;
}
}
}

return null;
