列出所有容器和blobs

Question

我正在使用容器和blobs处理Azure本地开发存储。我希望能够在列表框中显示我的所有容器和blobs，就像本地开发存储的树视图一样。这是我的代码：

public List<string> ListContainer()
    {
        List<string> blobs = new List<string>();

        // Retrieve storage account from connection string.
        CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
            CloudConfigurationManager.GetSetting("AzureStorageConnectionString"));

        // Create the blob client.
        CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

        //Get the list of the blob from the above container

        IEnumerable<CloudBlobContainer> containers = blobClient.ListContainers();

        foreach (CloudBlobContainer item in containers)
        {
            blobs.Add(string.Format("{0}", item.Uri.Segments[2]));
        }

        return blobs;
    }

这里我展示了我所有的容器。我需要显示每个容器所拥有的所有blob，以及子文件夹。

Answer 1

您迭代的是容器，而不是容器中的blob。在每个容器上，您需要调用ListBlobs。

您的代码将如下所示：

foreach (CloudBlobContainer item in containers)
    {
        foreach (IListBlobItem blob in item.ListBlobs()){
            blobs.Add(string.Format("{0}", blob.Uri.Segments[2]));
        }
    }

Answer 2

很高兴在这里见到你。你不需要Listcontainer，你需要创建容器和列表blob。首先，，我已经告诉过你，你需要为你的本地存储创建一个本地容器，如果没有，在哪里可以存储这些文件？您可以使用container.createIfNotExists();创建新的blob，并将文件上传到它的blob。或者从azurestorageexplorer.codeplex.com下载azurestorageexplorer，在azurestorageexplorer中创建本地容器。

这是我的简单示例：

   public partial class _Default : Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
        ListBox1.DataSource =ListBlob("mycontainer");
        ListBox1.DataBind();

                  }
        public List<string> ListBlob(string folder)
        {
            List<string> blobs = new List<string>();

            // Retrieve storage account from connection string.
            CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
                CloudConfigurationManager.GetSetting("StorageConnectionString"));

            // Create the blob client.
            CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

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

            // Loop over items within the container and output the length and URI.
            foreach (IListBlobItem item in container.ListBlobs(null, false))
            {
                if (item.GetType() == typeof(CloudBlockBlob))
                {
                    CloudBlockBlob blob = (CloudBlockBlob)item;

                    blobs.Add(string.Format("Block blob of length {0}: {1}", blob.Properties.Length, blob.Uri));

                }
                else if (item.GetType() == typeof(CloudPageBlob))
                {
                    CloudPageBlob pageBlob = (CloudPageBlob)item;

                    blobs.Add(string.Format("Page blob of length {0}: {1}", pageBlob.Properties.Length, pageBlob.Uri));

                }
                else if (item.GetType() == typeof(CloudBlobDirectory))
                {
                    CloudBlobDirectory directory = (CloudBlobDirectory)item;

                    blobs.Add(string.Format("Directory: {0}", directory.Uri)); ;
                }
            }
            return blobs;
        }

        protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            ListBox2.DataSource = ListBlob("mycontainer01");
            ListBox2.DataBind();
        }
    }

请确保在ListBox1上设置AutoPostBack="True“，请查看此处的更多信息表单：https://azure.microsoft.com/en-us/documentation/articles/storage-dotnet-how-to-use-blobs/。如果你有任何问题，请保持联系。
