下面的代码使用WindowsAzure.Storage nuget包返回容器列表：

public static class AzureBlobStorageClient
{
    public static CloudBlobClient GetClient(string AccountName = "foo", string AccountKey = "bar" )
    {
        try
        {

            var connectionString = $"DefaultEndpointsProtocol=https;AccountName={AccountName};AccountKey={AccountKey};EndpointSuffix=core.windows.net";
            CloudStorageAccount storageAccount = CloudStorageAccount.Parse(connectionString);
            CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
            IRetryPolicy exponentialRetryPolicy = new ExponentialRetry(TimeSpan.FromSeconds(2), 10);
            blobClient.DefaultRequestOptions.RetryPolicy = exponentialRetryPolicy;
            return blobClient;
        }
        catch (StorageException ex)
        {
            Console.WriteLine("Error returned from the service: {0}", ex.Message);
            throw;
        }
    }

    public static void DeleteContainer(CloudBlobContainer container)
    {
        var result = container.DeleteIfExistsAsync().Result;
    }

    public static List<CloudBlobContainer> GetContainers()
    {
        var client = GetClient();
        BlobContinuationToken continuationToken = null;
        List<CloudBlobContainer> results = new List<CloudBlobContainer>();
        do
        {
            var response = client.ListContainersSegmentedAsync(continuationToken).Result;
            continuationToken = response.ContinuationToken;
            results.AddRange(response.Results);
        }
        while (continuationToken != null);

        return results;
    }

}

当我运行这个程序时，我在客户端上得到以下错误。ListContainersSegmentedAsync（continuationToken）。结果：
System.AggregateException:'发生一个或多个错误。（此请求未被授权执行此操作。）'
并且我看不到如何设置请求的授权。
我的问题是如何通过这个错误消息
