Overloads

BeginUploadFromFile(String, AsyncCallback, Object)	Begins an asynchronous operation to upload a file to an append blob. If the blob already exists, it will be overwritten. Recommended only for single-writer scenarios.
BeginUploadFromFile(String, AccessCondition, BlobRequestOptions, OperationContext, AsyncCallback, Object)	Begins an asynchronous operation to upload a file to an append blob. If the blob already exists, it will be overwritten. Recommended only for single-writer scenarios.

BeginUploadFromFile(String, AsyncCallback, Object)

Begins an asynchronous operation to upload a file to an append blob. If the blob already exists, it will be overwritten. Recommended only for single-writer scenarios.

[Microsoft.Azure.Storage.DoesServiceRequest]
public virtual Microsoft.Azure.Storage.ICancellableAsyncResult BeginUploadFromFile (string path, AsyncCallback callback, object state);

[<Microsoft.Azure.Storage.DoesServiceRequest>]
abstract member BeginUploadFromFile : string * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult
override this.BeginUploadFromFile : string * AsyncCallback * obj -> Microsoft.Azure.Storage.ICancellableAsyncResult

Public Overridable Function BeginUploadFromFile (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

ICancellableAsyncResult

An ICancellableAsyncResult that references the asynchronous operation.

Implements

BeginUploadFromFile(String, AsyncCallback, Object)

Attributes: DoesServiceRequestAttribute

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 BeginAppendFromFile(String, AsyncCallback, Object).
