天青容器

Question

有人可以告訴我，爲什麼我們不能在一個容器內的容器內創建一個容器在天藍色的存儲？還有任何需要處理的方法，我們需要在Azure存儲中創建目錄層次結構？

Answer 1

您不能在容器中創建容器，因爲Windows Azure根本不支持容器容器（您應該將容器看作「磁盤驅動器」，就像您的磁盤驅動器C：\ disk）。但是通過CloudBlobDirectory類支持使用目錄。下面是Neil's blog一個例子：

protected void GetDirectoryList(String topLevelDirectoryName, String subDirectoryName) 
{ 
    CloudStorageAccount cloudStorageAccount = 
     CloudStorageAccount.FromConfigurationSetting(「DataConnectionString」); 
    CloudBlobClient cloudBlobClient = cloudStorageAccount.CreateCloudBlobClient(); 

    CloudBlobDirectory topLevelDirectory = cloudBlobClient.GetBlobDirectoryReferencetopLevelDirectoryName); 

    CloudBlobDirectory subDirectory = topLevelDirectory.GetSubdirectory(subDirectoryName); 

    IEnumerable<IListBlobItem> blobItems = subDirectory.ListBlobs(); 
    foreach (IListBlobItem blobItem in blobItems) 
    { 
     Uri uri = blobItem.Uri; 
    } 
}

下面是從我的課蔚藍的容器中的工作代碼（用於管理BLOB）的一個工作項目。
PLS和PLS注意，您在容器中的文件夾，並在容器中的BLOB文件的命名應該是小寫字母或者你可能有一個錯誤

     CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient(); 

     // Retrieve reference to a previously created container. 
     CloudBlobContainer container = blobClient.GetContainerReference(userId);

     { 
      blockBlob2.DownloadToStream(memoryStream); 
      text = System.Text.Encoding.UTF8.GetString(memoryStream.ToArray()); 
     } 
     return text; 
    } 

    public void DeleteBlobFile(string userId, string itemKey) 
    { 
     CloudBlobContainer container = Prerequisite(userId); 

     // Retrieve reference to a blob named "myblob.txt". 
     CloudBlockBlob blockBlob = container.GetBlockBlobReference(itemKey); 

     // Delete the blob. 
     blockBlob.Delete(); 
    } 

    } 
    }

到另一個容器內創建一個容器的最簡單方法對於Azure blob存儲，則是使用來自Cerebrata的稱爲Azure Explorer的免費Azure存儲管理工具。

它允許您通過創建一個新文件夾來創建容器。
