C# Azure Storage Blob Upload TransactionScope

Question

Is there somewhere a class to allow roll back with transactionscope on azure blockblob actions ?

I would like make this works:

  CloudBlockBlob blockBlob;

    private void UploadPicture(Stream iStream)
    {
        using(var ts = new TransactionScope())
        {
            blockBlob.UploadFromStream(iStream);

            throw new Exception();
            ts.Complete();
        }
    }

When the exception is raise, the uploaded file is not cancelled. If is not possible with transaction scope, how should I proceed ?

Answer 1

Azure Storage Client Library does not provide this support. If, however, cancellation support is acceptable for your scenario, you can use the UploadFromStreamAsync API with a CancellationToken. While it is asynchronously uploading the blob, you can cancel the operation. Depending on the operation's current progress, it will try to abort the upload.
