Question

我使用WindowsAzure.Storage.Blob找到了一些答案，但是此软件包已弃用。

所以我需要使用.net core从Azure获取Blob存储中的容器列表。

Answer 1

添加“ Azure.Storage.Blobs” NuGet程序包。

使用BlobServiceClient类

string connectionString = "";
BlobServiceClient client = new BlobServiceClient(connectionString);

使用GetBlobContainers或GetBlobContainersAsync检索容器：

//-------------------------------------------------
// List containers
//-------------------------------------------------
async static Task ListContainers(BlobServiceClient blobServiceClient, 
                                string prefix, 
                                int? segmentSize)
{
    string continuationToken = string.Empty;

    try
    {
        do
        {
            // Call the listing operation and enumerate the result segment.
            // When the continuation token is empty, the last segment has been returned
            // and execution can exit the loop.
            var resultSegment = 
                blobServiceClient.GetBlobContainersAsync(BlobContainerTraits.Metadata, prefix, default)
                .AsPages(continuationToken, segmentSize);
            await foreach (Azure.Page<BlobContainerItem> containerPage in resultSegment)
            {
                foreach (BlobContainerItem containerItem in containerPage.Values)
                {
                    Console.WriteLine("Container name: {0}", containerItem.Name);
                }

                // Get the continuation token and loop until it is empty.
                continuationToken = containerPage.ContinuationToken;

                Console.WriteLine();
            }

        } while (continuationToken != string.Empty);
    }
    catch (RequestFailedException e)
    {
        Console.WriteLine(e.Message);
        Console.ReadLine();
        throw;
    }
}

如果要搜索以某些前缀开头的容器，则前缀参数是可选的。
