Helper class (C#) returns a list of filenames for all files in a given blob container (Azure Storage)

StorageHelper.cs

public async Task<List<string>> GetBlobFileListAsync(string storageConnectionString, string containerName)
{
	try
	{
		// Get Reference to Blob Container
		CloudStorageAccount storageAccount = CloudStorageAccount.Parse(storageConnectionString);
		CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
		CloudBlobContainer container = blobClient.GetContainerReference(containerName);

		// Fetch info about files in the container
		// Note: Loop with BlobContinuationToken to fetch results in pages. Pass null as currentToken to fetch all results.
		BlobResultSegment resultSegment = await container.ListBlobsSegmentedAsync(currentToken: null);
		IEnumerable<IListBlobItem> blobItems = resultSegment.Results;

		// Extract the URI of the files into a new list
		List<string> fileUris = new List<string>();
		foreach (var blobItem in blobItems)
		{
			fileUris.Add(blobItem.StorageUri.PrimaryUri.ToString());
		}
		return fileUris;
	}
	catch (System.Exception e)
	{
		// Note: When using ASP.NET Core Web Apps, to output to streaming logs, use ILogger rather than System.Diagnostics
		logger.LogError($"Exception occurred while attempting to list files on server: {e.Message}");
		return null;         // or throw e; if you want to bubble the exception up to the caller
	}
