[Microsoft.Azure.Storage.DoesServiceRequest]
public virtual Microsoft.Azure.Storage.ICancellableAsyncResult BeginAppendBlock(System.IO.Stream blockData, AsyncCallback callback, object state);

[<Microsoft.Azure.Storage.DoesServiceRequest>]
abstract member BeginAppendBlock : System.IO.Stream * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
override this.BeginAppendBlock : System.IO.Stream * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult

Public Overridable Function BeginAppendBlock (blockData As Stream, callback As AsyncCallback, state As Object) As ICancellableAsyncResult

Parameters

blockData: System.IO.Stream

A System.IO.Stream object that provides the data for the block.

callback: System.AsyncCallback

An System.AsyncCallback delegate that will receive notification when the asynchronous operation completes.

state: System.Object

A user-defined object that will be passed to the callback delegate.

Returns

ICancellableAsyncResult

An ICancellableAsyncResult that references the asynchronous operation.

Attributes: DoesServiceRequestAttribute

Applies to

BeginAppendBlock(Stream, Checksum, AsyncCallback, Object)

Begins an asynchronous operation to commit a new block of data to the end of the blob.

[Microsoft.Azure.Storage.DoesServiceRequest]
public virtual Microsoft.Azure.Storage.ICancellableAsyncResult BeginAppendBlock(System.IO.Stream blockData, Microsoft.Azure.Storage.Shared.Protocol.Checksum contentChecksum, AsyncCallback callback, object state);

[<Microsoft.Azure.Storage.DoesServiceRequest>]
abstract member BeginAppendBlock : System.IO.Stream * Microsoft.Azure.Storage.Shared.Protocol.Checksum * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
override this.BeginAppendBlock : System.IO.Stream * Microsoft.Azure.Storage.Shared.Protocol.Checksum * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult

Public Overridable Function BeginAppendBlock (blockData As Stream, contentChecksum As Checksum, callback As AsyncCallback, state As Object) As ICancellableAsyncResult

Parameters

blockData: System.IO.Stream

A System.IO.Stream object that provides the data for the block.

contentChecksum: Checksum

A hash value used to ensure transactional integrity. May be null or Checksum.None

callback: System.AsyncCallback

An System.AsyncCallback delegate that will receive notification when the asynchronous operation completes.

state: System.Object

A user-defined object that will be passed to the callback delegate.

Returns

ICancellableAsyncResult

An ICancellableAsyncResult that references the asynchronous operation.

Attributes: DoesServiceRequestAttribute

Remarks

Clients may send the content checksum headers for a given operation as a means to ensure transactional integrity over the wire. The contentChecksum parameter permits clients who already have access to a pre-computed checksum value for a given byte range to provide it. If the BlobRequestOptions.UseTransactionalMd5 or BlobRequestOptions.UseTransactionalCrc64 properties are set to true and the corresponding content parameter is set to null, then the client library will calculate the checksum value internally.
