CloudAppendBlob.AppendFromByteArrayAsync Method

Definition

Overloads

AppendFromByteArrayAsync(Byte[], Int32, Int32, AccessCondition, BlobRequestOptions, OperationContext, IProgress<StorageProgress>, CancellationToken)

Initiates an asynchronous operation to upload the contents of a byte array to an append blob.This API should be used strictly in a single writer scenario because the API internally uses the append-offset conditional header to avoid duplicate blocks which does not work in a multiple writer scenario.

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.

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

A Task object that represents the asynchronous operation.
