override this.AppendBlockAsync : System.IO.Stream * string -> System.Threading.Tasks.Task<int64>
Public Overridable Function AppendBlockAsync (blockData As Stream, Optional contentMD5 As String = Nothing) As Task(Of Long)

Parameters

blockData
Stream

A Stream object that provides the data for the block.

contentMD5
String

An optional hash value used to ensure transactional integrity. May be null or an empty string.

Returns

A Task object that represents the asynchronous operation.

Attributes

Remarks

Clients may send the Content-MD5 header for a given Append Block operation as a means to ensure transactional integrity over the wire. The contentMD5 parameter permits clients who already have access to a pre-computed MD5 value for a given byte range to provide it. If the BlobRequestOptions.UseTransactionalMd5 property is set to true and the contentMD5 parameter is set to null, then the client library will calculate the MD5 value internally.

Applies to
