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