Azure Storage move blob to other container

i'm looking for an approach to move a blob in MS Azure from one container to another. The only solution I found is to use the Azure Storage Data Movement Library, but this seems to work between different accounts. I would like to move the blob within the same account to an other container.

I have not used Azure Storage Data Movement Library but I am pretty sure that it will work in the same storage account as well.

Coming to your question, since Move operation is not natively supported by Azure Storage what you can do is implement this by invoking Copy Blob followed by Delete Blob. In general Copy operation is async however when a blob is copied in same storage account, it is a synchronous operation i.e. copy happens instantaneously. Please see sample code below which does just this:

    static void MoveBlobInSameStorageAccount()
        var cred = new StorageCredentials(accountName, accountKey);
        var account = new CloudStorageAccount(cred, true);
        var client = account.CreateCloudBlobClient();
        var sourceContainer = client.GetContainerReference("source-container-name");
        var sourceBlob = sourceContainer.GetBlockBlobReference("blob-name");
        var destinationContainer = client.GetContainerReference("destination-container-name");
        var destinationBlob = destinationContainer.GetBlockBlobReference("blob-name");

However, please keep in mind that you use this code only for moving blobs in the same storage account. For moving blobs across storage account, you need to ensure that copy operation is complete before you delete the source blob.
