Public Overridable Function UploadFromByteArrayAsync (buffer As Byte(), index As Integer, count As Integer) As Task

Parameters

buffer

Byte[]

An array of bytes.

index

Int32

The zero-based byte offset in buffer at which to begin uploading bytes to the blob.

count

Int32

The number of bytes to be written to the blob.

Returns

Task

A Task object that represents the asynchronous operation.

Implements

UploadFromByteArrayAsync(Byte[], Int32, Int32)

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. To append data to an append blob that already exists, see AppendFromByteArrayAsync(Byte[], Int32, Int32).

UploadFromByteArrayAsync(Byte[], Int32, Int32, CancellationToken)

Initiates an asynchronous operation to upload the contents of a byte array to an append blob. If the blob already exists, it will be overwritten. Recommended only for single-writer scenarios.
