<DoesServiceRequestAttribute>
Public Overridable Function AppendFromByteArrayAsync (
	buffer As Byte(),
	index As Integer,
	count As Integer
) As Task

Parameters

buffer

Type: System.Byte[]array<System::Byte>^System.Byte[]System.Byte()

An array of bytes.

index

Type: System.Int32System::Int32System.Int32System.Int32

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

count

Type: System.Int32System::Int32System.Int32System.Int32

The number of bytes to be written to the blob.

Return Value

Type: System.Threading.Tasks.TaskSystem.Threading.Tasks::Task^System.Threading.Tasks.TaskSystem.Threading.Tasks.Task

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.
