abstract member BeginAppendFromFile : string * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
override this.BeginAppendFromFile : string * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResultPublic Overridable Function BeginAppendFromFile (path As String, callback As AsyncCallback, state As Object) As ICancellableAsyncResultParameters
- path
- String
A string containing the file path providing the blob content.
- 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. If you have a single-writer scenario, see AbsorbConditionalErrorsOnRetry to determine whether setting this flag to true is acceptable for your scenario.
Applies to
BeginAppendFromFile(String, AccessCondition, BlobRequestOptions, OperationContext, AsyncCallback, Object)
