CloudAppendBlob.BeginAppendFromFile Method

Definition

Overloads

BeginAppendFromFile(String, AsyncCallback, Object)

Begins an asynchronous operation to append a file to an append blob. Recommended only for single-writer scenarios.

BeginAppendFromFile(String, AccessCondition, BlobRequestOptions, OperationContext, AsyncCallback, Object)

Begins an asynchronous operation to append a file to an append blob. Recommended only for single-writer scenarios.

BeginAppendFromFile(String, AccessCondition, BlobRequestOptions, OperationContext, IProgress<StorageProgress>, AsyncCallback, Object)

Begins an asynchronous operation to append a file to an append blob. Recommended only for single-writer scenarios.

BeginAppendFromFile(String, AsyncCallback, Object)

Begins an asynchronous operation to append a file to an append blob. Recommended only for single-writer scenarios.

[Microsoft.Azure.Storage.DoesServiceRequest]
public virtual Microsoft.Azure.Storage.ICancellableAsyncResult BeginAppendFromFile (string path, AsyncCallback callback, object state);
[<Microsoft.Azure.Storage.DoesServiceRequest>]
abstract member BeginAppendFromFile : string * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
override this.BeginAppendFromFile : string * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
Public Overridable Function BeginAppendFromFile (path As String, callback As AsyncCallback, state As Object) As ICancellableAsyncResult

Parameters

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.
