使用全局CloudStorageAccount变量

Question

我对CloudStorageAccount变量有疑问。我一直在我的代码中经常使用和声明它，我想知道它是否会导致冲突，将它声明为全局变量，并在每个函数中使用它。我将用一个简单的例子来证明我的问题。

public class AzureQueueSvc : IQueueSvc
{
    DoclQueue _queue;

    public AzureQueueSvc(DoclQueue queue)
    {
        _queue = queue;
        _queue.Connectionstring = ConfigurationManager.AppSettings["Microsoft.ServiceBus.ConnectionString"];
    }

    public CloudQueue GetQueue { get; }

    public void CreateQueue()
    {
        CloudStorageAccount account = CloudStorageAccount.Parse(_queue.Connectionstring);
        CloudQueueClient queueClient = account.CreateCloudQueueClient();
        CloudQueue queue = queueClient.GetQueueReference(_queue.Name);
        queue.CreateIfNotExists();
    }

    public bool QueueExists()
    {
        CloudStorageAccount account = CloudStorageAccount.Parse(_queue.Connectionstring);
        CloudQueueClient queueClient = account.CreateCloudQueueClient();
        CloudQueue queue = queueClient.GetQueueReference(_queue.Name);

        if (queue.Exists())
            return true;
        else
            return false;
    }

    public void SendMessage(DoclMessage message)
    {
        CloudStorageAccount account = CloudStorageAccount.Parse(_queue.Connectionstring);
        CloudQueueClient queueClient = account.CreateCloudQueueClient();
        CloudQueue queue = queueClient.GetQueueReference(_queue.Name);
        queue.CreateIfNotExists();

        CloudQueueMessage msg = new CloudQueueMessage(string.Format(message.ToString()));
        queue.AddMessage(msg);

    }
}

正如您所看到的，我必须声明CloudStorageAccount，CloudQueueClient＆amp; CloudQueue 3次。将它们声明为全局变量会导致冲突，并在我的方法中分享它们的用法吗？
