override this.UploadFromByteArrayAsync : byte[] * int * int -> System.Threading.Tasks.TaskPublic Overridable Function UploadFromByteArrayAsync (buffer As Byte(), index As Integer, count As Integer) As TaskParameters
- 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
A Task object that represents the asynchronous operation.

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).
