| BeginAppendFromByteArray(Byte[], Int32, Int32, AsyncCallback, Object) |
Begins an asynchronous operation to append the contents of a byte array to an append blob. Recommended only for single-writer scenarios. |
| BeginAppendFromByteArray(Byte[], Int32, Int32, AccessCondition, BlobRequestOptions, OperationContext, AsyncCallback, Object) |
Begins an asynchronous operation to append the contents of a byte array to an append blob. Recommended only for single-writer scenarios. |
BeginAppendFromByteArray(Byte[], Int32, Int32, AsyncCallback, Object)

abstract member BeginAppendFromByteArray : byte[] * int * int * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
override this.BeginAppendFromByteArray : byte[] * int * int * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResultPublic Overridable Function BeginAppendFromByteArray (buffer As Byte(), index As Integer, count As Integer, callback As AsyncCallback, state As Object) As ICancellableAsyncResultParameters
- buffer
- Byte[]
An array of bytes.
- index
- Int32
The zero-based byte offset in buffer at which to begin uploading bytes to the blob.
- count
- Int32
The number of bytes to be written to the blob.
- 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
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.

- buffer
- Byte[]
An array of bytes.
- index
- Int32
The zero-based byte offset in buffer at which to begin uploading bytes to the blob.
- count
- Int32
The number of bytes to be written to the blob.
- accessCondition
- AccessCondition
An AccessCondition object that represents the condition that must be met in order for the request to proceed.
- 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.
- callback
- AsyncCallback
An AsyncCallback delegate that will receive notification when the asynchronous operation completes.
- state

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.
