Question

我对我的项目有疑问......我需要知道如何从Windows Azure blob存储中列出所有文件夹（在字符串列表或其他内容中）...我已经拥有了我的BlobClient以及与Azure的连接存储

谁可以帮我解决这个“问题”？

Answer 1

试试这段代码。它使用 Storage Client库2.0.3 ：

        CloudStorageAccount storageAccount = CloudStorageAccount.DevelopmentStorageAccount;
        CloudBlobContainer blobContainer = storageAccount.CreateCloudBlobClient().GetContainerReference("wad-control-container");
        string blobPrefix = null;
        bool useFlatBlobListing = false;
        var blobs = blobContainer.ListBlobs(blobPrefix, useFlatBlobListing, BlobListingDetails.None);
        var folders = blobs.Where(b => b as CloudBlobDirectory != null).ToList();
        foreach (var folder in folders)
        {
            Console.WriteLine(folder.Uri);
        }

如果您使用 Storage Client Library 1.8（即2.0之前的版本），请尝试以下代码：

        var storageAccount = CloudStorageAccount.DevelopmentStorageAccount;
        cloudBlobClient = storageAccount.CreateCloudBlobClient();
        CloudBlobContainer container = cloudBlobClient.GetContainerReference("wad-control-container");
        IEnumerable<IListBlobItem> blobs = container.ListBlobs(new BlobRequestOptions()
        {
            UseFlatBlobListing = false,
        });
        var folders = blobs.Where(b => b as CloudBlobDirectory != null);

        foreach (var folder in folders)
        {
            Console.WriteLine(folder.Uri);
        }

我在我的项目中使用了这个解决方案

// Retrieve reference to the container.
CloudBlobContainer container = BlobClient.GetContainerReference(lvContainer.SelectedItems[0].Text);

//Loop over VIRTUAL directories within the container
foreach (IListBlobItem item in container.ListBlobs())
{
      if (item.GetType() == typeof(CloudBlobDirectory))
      {
           CloudBlobDirectory directory = (CloudBlobDirectory)item;
           string[] uri = directory.Uri.ToString().Split('/');
           ListViewItem dir = new ListViewItem();
           dir.Text = uri[uri.Length-2];
           dir.ImageIndex = 0;

           ListViewItem.ListViewSubItem subitem = new ListViewItem.ListViewSubItem();
           subitem.Text = String.Empty; //item.Properties.LastModifiedUtc.ToString();
           dir.SubItems.Add(subitem);

           subitem = new ListViewItem.ListViewSubItem();
           subitem.Text = String.Empty; //item.Properties.Length + " bytes";
           dir.SubItems.Add(subitem);

           lvBlob.Items.Add(dir);
       }
}

在我的情况下，我使用

在listView中显示结果，列出大小和日期

(item.GetType() == typeof(CloudBlockBlob))

和

(item.GetType() == typeof(CloudPageBlob))

在同一个foreach中列出每个虚拟文件夹层，BlockBlobs和PageBlobs不同。希望这会有所帮助。
