AppendFromFileAsync(String)

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

AppendFromFileAsync(String, CancellationToken)

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

AppendFromFileAsync(String, AccessCondition, BlobRequestOptions, OperationContext)

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

AppendFromFileAsync(String, AccessCondition, BlobRequestOptions, OperationContext, CancellationToken)

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

AppendFromFileAsync(String, AccessCondition, BlobRequestOptions, OperationContext, IProgress<StorageProgress>, CancellationToken)

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

AppendFromFileAsync(String)

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

[Microsoft.Azure.Storage.DoesServiceRequest]
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.Task
Public Overridable Function AppendFromFileAsync (path As String) As Task

Parameters

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.

[Microsoft.Azure.Storage.DoesServiceRequest]
public virtual System.Threading.Tasks.Task AppendFromFileAsync (string path, System.Threading.CancellationToken cancellationToken);

abstract member AppendFromFileAsync : string * System.Threading.CancellationToken -> System.Threading.Tasks.Task
override this.AppendFromFileAsync : string * System.Threading.CancellationToken -> System.Threading.Tasks.Task
Public Overridable Function AppendFromFileAsync (path As String, cancellationToken As CancellationToken) As Task

Parameters

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.

Attributes

Public Overridable Function AppendFromFileAsync (path As String, accessCondition As AccessCondition, options As BlobRequestOptions, operationContext As OperationContext) As Task

Parameters

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.
