c# - Azure Blob 存储无效帐户字符串错误

Question

我在 ASP.NET MVC5 中连接到我的 Azure Blob 存储帐户时遇到问题。

我查看了一些教程，并提出了一个带有 BlobStorageContainerFactory 的简单存储库模式，以便我可以注入(inject)命名存储库。当我使用 Azure 存储本地开发模拟器时，此代码运行良好。这是工厂的代码:

    public class BlobStorageContainerFactory
    {
        private CloudStorageAccount _storageAccount;
        private CloudBlobClient _blobClient;
        public CloudBlobContainer Get(string containerName)
        {
            //i want to get the connection string from the web.config eventually
            //_storageAccount = CloudStorageAccount.Parse(ConfigurationManager.ConnectionStrings["BattleBornPrepsStorageConnection"].ConnectionString);

            //error occurs here
            _storageAccount = CloudStorageAccount.Parse("DefaultEndpointsProtocol=http;AccountName=myaccountnamealllower;AccountKey=theprimaryaccountkeyfromazuremanagementportal;");

            _blobClient = _storageAccount.CreateCloudBlobClient();
            var container = _blobClient.GetContainerReference(containerName);

            if (container.CreateIfNotExist())
            {
                // configure container for public access
                var permissions = container.GetPermissions();
                permissions.PublicAccess = BlobContainerPublicAccessType.Container;
                container.SetPermissions(permissions);
            }

            return container;
        }
    }

当我尝试解析连接字符串时出现错误:

An exception of type 'System.FormatException' occurred in Microsoft.WindowsAzure.StorageClient.dll but was not handled in user code

Additional information: Invalid account string.

看起来 blob 存储连接字符串不允许在字符串末尾出现 ; 。

它们的顺序并不重要。
