How to create the copy of container on Azure C#

Question

I have requirement create the copy of container.

I have using the below code.

First create the container and then copy the blob file.

CloudStorageAccount storageAccount = new CloudStorageAccount(new StorageCredentials(accountName, accountKey), true);

CloudBlobClient cloudBlobClient = storageAccount.CreateCloudBlobClient();

CloudBlobContainer sourceContainer = cloudBlobClient.GetContainerReference(containerName);

CloudBlobContainer targetContainer = cloudBlobClient.GetContainerReference(targetContainerName);

string blobName = "<Blob Name e.g. myblob.txt>";

CloudBlockBlob sourceBlob = sourceContainer.GetBlockBlobReference(blobName);

CloudBlockBlob targetBlob = targetContainer.GetBlockBlobReference(blobName);

targetBlob.StartCopyFromBlob(sourceBlob);

but Its taking the much time. when blob file are more thousands.

so i want to copy full container not one by one blob files.
