public virtual System.Threading.Tasks.Task AppendFromFileAsync (string path);[<Microsoft.Azure.Storage.DoesServiceRequest>]
abstract member AppendFromFileAsync : string -> System.Threading.Tasks.Task
override this.AppendFromFileAsync : string -> System.Threading.Tasks.TaskPublic Overridable Function AppendFromFileAsync (path As String) As TaskParameters
- path
- String
A string containing the file path providing the blob content.
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.
Applies to
AppendFromFileAsync(String, CancellationToken)
Initiates an asynchronous operation to append a file to an append blob. Recommended only for single-writer scenarios.

- path
- String
A string containing the file path providing the blob content.
- cancellationToken
- CancellationToken
A CancellationToken to observe while waiting for a task to complete.
Returns
A Task object that represents the asynchronous operation.

- path
- String
A string containing the file path providing the blob content.
- 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.
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.
