I have an Azure container 'MyContainer' then 'under' it, I have 'subfolders' called ProcessingFiles. So the 'structure' looks like this

MyContainerProcessingFilesSampleFile.xml

I want to delete 'SampleFile.xml' - but when I run the following code the 'ProcessingFiles' folder is also deleted.

 //connect to azure  container

            var storageAccount = CloudStorageAccount.Parse(_BlobConnectionstring);



            var myClient = storageAccount.CreateCloudBlobClient();

            var container = myClient.GetContainerReference(MyContainer");



            container.CreateIfNotExists(BlobContainerPublicAccessType.Blob);



            _blobabspath = container.Uri.AbsoluteUri;



            foreach (IListBlobItem blobItem in container.ListBlobs())

            {

                if (blobItem is CloudBlobDirectory)

                {

                    CloudBlobDirectory directory = (CloudBlobDirectory)blobItem;

                    if (directory.Uri.AbsoluteUri.Contains("ProcessingFolder))

                    {

                        IEnumerable<IListBlobItem> blobs = directory.ListBlobs(true);

                        ICloudBlob bi;

                        foreach (var blob in blobs)

                        {

                            if (blob is CloudBlockBlob)

                            {

                                bi = blob as CloudBlockBlob;

                                if (bi.Name.Contains(".xml"))

                                {

                                   Log.Info($"Deleting XML file : {bi.Name} from {_processingfolder}");

                                   bi.Delete();

                                }

                            }

                        }

                    }

                }

            }

How do I JUST delete the single XML file - and not include the subfolder 'ProcessingFolder'?

What am I missing? thx in advance

Azure Storage doesn't have subfolders, only containers and blobs. Azure Storage gives you something that looks like folders via the delimiter character (letting you do specific searches, for instance).

Your blob's name is actually ProcessingFilesSampleFile.xml. This is why it appears that the subfolder disappears when you delete the blob.

Just to drive the point home a bit further: let's say you had a thousand blobs, spread across multiple "subfolders" and you tried filtering on just the one subfolder (ProcessingFiles in your case). The search would still scan all thousand blobs, filtering on the prefix part of the name you specified.
