- length
- Int64
The number of bytes to write from the source stream at its current position.
- accessCondition
- AccessCondition
An AccessCondition object that represents the condition that must be met in order for the request to proceed. If null, no condition is used.
- options
- BlobRequestOptions
A BlobRequestOptions object that specifies additional options for the request.
- operationContext
- OperationContext
An OperationContext object that represents the context for the current operation.
- progressHandler
- IProgress<StorageProgress>
A IProgress<T> object to handle StorageProgress messages.
- cancellationToken
- CancellationToken
A CancellationToken to observe while waiting for a task to complete.
Returns
A Task object that represents the asynchronous operation.
- Attributes
Remarks
Use this method only in single-writer scenarios. Internally, this method uses the append-offset conditional header to avoid duplicate blocks, which may cause problems in multiple-writer scenarios. If you have a single-writer scenario, see AbsorbConditionalErrorsOnRetry to determine whether setting this flag to true is acceptable for your scenario. To append data to an append blob that already exists, see AppendFromStreamAsync(Stream, Int64, AccessCondition, BlobRequestOptions, OperationContext, CancellationToken).
