如何从 Azure Blob 存储 C# 中的文件 URL 获取容器名称

Question

We are able to get container name using the code below:

new CloudBlobContainer(url).Name

But this method works only if the URL is container base URL.

If we are trying to pass the URL of a file and try to get the container name, the code will not return data as expected. In this case, we have to use the CloudBlockBlob object.

new CloudBlockBlob(new Uri(Url)).Container.Name

Is there any method to get a container name that will work for URLs listed below:

http://127.0.0.1:10000/devstoreaccount1/10d59357-b4d1-41e8-ba2a-d92964e1ac53

Answer 1

Older SDK (9.3.3)

If you're using older SDK (9.3.3), You can use BlobClient and the name of the blob container will be available in BlobContainerName property.

BlobClient client = new BlobClient(new Uri(url));

Newer SDK (12.2.0)

For newer SDK (12.2.0), you can use BlobUriBuilder and the name of the blob container will be available in BlobContainerName property.

BlobUriBuilder blobUriBuilder = new BlobUriBuilder(new Uri(url));

string blobUri = "http://127.0.0.1:10000/devstoreaccount1/10d59357-b4d1-41e8-ba2a-d92964e1ac53/temp/1.txt";    
Uri uri = new Uri(blobUri);

string containerName = uri.Segments[1];

string containerUri = uri.GetLeftPart(UriPartial.Authority) + containerName;

This should help you
