BeginWritePages(Uri, Int64, Int64, Int64, Checksum, AccessCondition, AccessCondition, BlobRequestOptions, OperationContext, AsyncCallback, Object)

Begins an asynchronous operation to write pages to a page blob.

BeginWritePages(Stream, Int64, Checksum, AsyncCallback, Object)

Begins an asynchronous operation to write pages to a page blob.

[Microsoft.Azure.Storage.DoesServiceRequest]

[<Microsoft.Azure.Storage.DoesServiceRequest>]
abstract member BeginWritePages : System.IO.Stream * int64 * Microsoft.Azure.Storage.Shared.Protocol.Checksum * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
override this.BeginWritePages : System.IO.Stream * int64 * Microsoft.Azure.Storage.Shared.Protocol.Checksum * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
Public Overridable Function BeginWritePages (pageData As Stream, startOffset As Long, contentChecksum As Checksum, callback As AsyncCallback, state As Object) As ICancellableAsyncResult

Parameters

pageData
Stream

A Stream object providing the page data.

startOffset
Int64

The offset at which to begin writing, in bytes. The offset must be a multiple of 512.

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

An ICancellableAsyncResult that references the asynchronous operation.

Attributes

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.

Applies to

BeginWritePages(Stream, Int64, Checksum, AccessCondition, BlobRequestOptions, OperationContext, AsyncCallback, Object)
