每当我尝试检查队列中是否有任何消息时，我都会收到“对象引用未设置为对象的实例”。我相信可能是因为我的队列过期并关闭了。

msg = this.queue.GetMessage(); 如果（味精！= null）

这是我的天蓝色模拟器错误：

Diagnostics]: Error when reading control container:Microsoft.WindowsAzure.StorageClient.StorageClientException: ERROR ---> System.Net.WebException: The remote server returned an error: (400) Bad Request.
   at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
   at Microsoft.WindowsAzure.StorageClient.EventHelper.ProcessWebResponse(WebRequest req, IAsyncResult asyncResult, EventHandler`1 handler, Object sender)
   --- End of inner exception stack trace ---
   at Microsoft.WindowsAzure.StorageClient.Tasks.Task`1.get_Result()
   at Microsoft.WindowsAzure.StorageClient.Tasks.Task`1.ExecuteAndWait()
   at Microsoft.WindowsAzure.Diagnostics.ControlChannel.GetControlContainer()
[Diagnostics]: Polling for configuration changes:System.NullReferenceException: Object reference not set to an instance of an object.

我对 OnStart 方法所做的是：

ServicePointManager.DefaultConnectionLimit = 12;

        // read storage account configuration settings
        CloudStorageAccount.SetConfigurationSettingPublisher((configName,

configSetter) => { configSetter(RoleEnvironment.GetConfigurationSettingValue(configName)); }); var storageAccount = CloudStorageAccount.FromConfigurationSetting("DataConnectionString");

        // initialize blob storage
        CloudBlobClient blobStorage = storageAccount.CreateCloudBlobClient();
        this.container = blobStorage.GetContainerReference("userpictures");

        // initialize queue storage 
        CloudQueueClient queueStorage = storageAccount.CreateCloudQueueClient();
        this.queue = queueStorage.GetQueueReference("pictureminiatures");
        this.queue.CreateIfNotExist();

你能帮我找出我在哪里做错了吗？
