BlockBlobClient.GetBlockListAsync Method

Definition

Namespace:

Azure.Storage.Blobs.Specialized

Assembly:

Azure.Storage.Blobs.dll

Package:

Azure.Storage.Blobs v12.23.0

Source:

BlockBlobClient.cs

The GetBlockListAsync(BlockListTypes, String, BlobRequestConditions, CancellationToken) operation operation retrieves the list of blocks that have been uploaded as part of a block blob. There are two block lists maintained for a blob. The Committed Block list has blocks that have been successfully committed to a given blob with CommitBlockListAsync(IEnumerable<String>, CommitBlockListOptions, CancellationToken). The Uncommitted Block list has blocks that have been uploaded for a blob using Azure.Storage.Blobs.Specialized.BlockBlobClient.StageBlockAsync(System.String,System.IO.Stream,System.Byte[],Azure.Storage.Blobs.Models.BlobRequestConditions,System.IProgress{System.Int64},System.Threading.CancellationToken), but that have not yet been committed. These blocks are stored in Azure in association with a blob, but do not yet form part of the blob.

Parameters

blockListTypes

BlockListTypes

Specifies whether to return the list of committed blocks, the list of uncommitted blocks, or both lists together. If you omit this parameter, Get Block List returns the list of committed blocks.

snapshot

String

Optionally specifies the blob snapshot to retrieve the block list from. For more information on working with blob snapshots, see Create a snapshot of a blob.

conditions

BlobRequestConditions

Optional BlobRequestConditions to add conditions on retrieving the block list.

cancellationToken

CancellationToken

Optional CancellationToken to propagate notifications that the operation should be cancelled.

Returns

Task<Response<BlockList>>

A Response<T> describing requested block list.

Remarks

A RequestFailedException will be thrown if a failure occurs.
