Deleting a folder from blob container

Question

I need to delete a folder from a blob container in Azure storage account. The folder structure is as follows:

container -> failed -> profiles

I am connecting to the container as follows:

CloudBlobClient blobClient = StorageAccountManager.getStorageAccount(ConnectionString));
var container = blobClient.GetContainerReference(container_name);

I am trying to refer to the specific folder as follows:

var blob = container.GetBlockBlobReference(failed + "/" + directory);

I also tried the follows ways:

((CloudBlob)blob).DeleteIfExists(); 
blob.DeleteIfExists();
blob.DeleteAsync();

but none of these are deleting the folder in my blob storage. Am I missing something or am I doing something wrong?

You need to use 'GetDirectoryReference("your folder name")' and then use deleteIfExists — Llazar

@Llazar this link worked. is it possible to parse through all the folders to check in which folder this folder is present? — Harry

Programatically is posible to iterate through folders files but you need to remember that the Azure Storage doesn't have the sense of folders. — Llazar

Folders in Azure Storage aren't really created or deleted, they exist as long as there are blobs stored in them. The way to delete a folder is to retrieve all blobs in it using ListBlobsSegmentedAsync and calling DeleteIfExists() on each of them.
