从Microsoft.Azure.Storage.Blob迁移到Azure.Storage.Blob-缺少目录概念

以下是在不同版本的NuGet软件包之间迁移的重要指南: https://github.com/Azure/azure-sdk-for-net/blob/Azure.Storage.Blobs_12.6.0/sdk/storage/Azure.Storage.Blobs/README.md https://elcamino.cloud/articles/2020-03-30-azure-storage-blobs-net-sdk-v12-upgrade-guide-and-tips.html

但是,我正在努力迁移代码中的以下概念:

// Return if a directory exists:
container.GetDirectoryReference(path).ListBlobs().Any();

其中GetDirectoryReference不被理解,并且似乎没有直接翻译

此外,CloudBlobDirectory的概念似乎还没有进入Azure.Storage.Blobs,例如。

        private static long GetDirectorySize(CloudBlobDirectory directoryBlob) {
            long size = 0;

            foreach (var blobItem in directoryBlob.ListBlobs()) {
                if (blobItem is BlobClient)
                    size += ((BlobClient) blobItem).GetProperties().Value.ContentLength;

                if (blobItem is CloudBlobDirectory)
                    size += GetDirectorySize((CloudBlobDirectory) blobItem);
            }

            return size;
        }
