Public Overridable Function UploadFromFileAsync (path As String, accessCondition As AccessCondition, options As BlobRequestOptions, operationContext As OperationContext, cancellationToken As CancellationToken) 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.

cancellationToken

CancellationToken

A CancellationToken to observe while waiting for a task to complete.

Returns

Task

A Task object that represents the asynchronous operation.

Implements

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

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

UploadFromFileAsync(String, AccessCondition, BlobRequestOptions, OperationContext)
