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

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

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

Parameters

blockId

String

A Base64-encoded string that identifies the block.

blockData

Stream

A 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

AsyncCallback

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

state

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.

BeginPutBlock(String, Uri, Nullable<Int64>, Nullable<Int64>, Checksum, AsyncCallback, Object)

Begins an asynchronous operation to upload a single block.

Public Overridable Function BeginPutBlock (blockId As String, sourceUri As Uri, offset As Nullable(Of Long), count As Nullable(Of Long), contentChecksum As Checksum, callback As AsyncCallback, state As Object) As ICancellableAsyncResult

Parameters

blockId

String

A Base64-encoded string that identifies the block.

sourceUri

Uri

A Uri specifying the absolute URI to the source blob.

offset

Nullable<Int64>

The byte offset at which to begin returning content.

count

Nullable<Int64>

The number of bytes to return, or null to return all bytes through the end of the blob.

contentChecksum

Checksum

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

callback

AsyncCallback

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

state

Object

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

Returns

ICancellableAsyncResult

An ICancellableAsyncResult that references the asynchronous operation.
