public virtual System.Threading.Tasks.Task UploadFromStreamAsync (System.IO.Stream source, long length, Microsoft.Azure.Storage.AccessCondition accessCondition, Microsoft.Azure.Storage.Blob.BlobRequestOptions options, Microsoft.Azure.Storage.OperationContext operationContext, IProgress<Microsoft.Azure.Storage.Core.Util.StorageProgress> progressHandler, System.Threading.CancellationToken cancellationToken);

Public Overridable Function UploadFromStreamAsync (source As Stream, length As Long, accessCondition As AccessCondition, options As BlobRequestOptions, operationContext As OperationContext, progressHandler As IProgress(Of StorageProgress), cancellationToken As CancellationToken) As Task

Parameters

source: Stream

A Stream object providing the blob content.

length: Int64

The number of bytes to write from the source stream at its current position.

accessCondition: AccessCondition

An AccessCondition object that represents the condition that must be met in order for the request to proceed. If null, no condition is used.

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.

progressHandler: IProgress<StorageProgress>

A IProgress<T> object to handle StorageProgress messages.

cancellationToken: CancellationToken

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

Returns

Task

A Task object that represents the asynchronous operation.

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 AppendFromStreamAsync(Stream, Int64, AccessCondition, BlobRequestOptions, OperationContext, CancellationToken).
