Public Overridable Function AppendFromStreamAsync (source As Stream, length As Long, accessCondition As AccessCondition, options As BlobRequestOptions, operationContext As OperationContext) As Task

Parameters

source
Stream

A Stream object providing the blob content.

length
Int64

The number of bytes to write from the source stream at its current position.

accessCondition
AccessCondition

An AccessCondition object that represents the condition that must be met in order for the request to proceed. If null, no condition is used.

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.

Returns

A Task object that represents the asynchronous operation.

Attributes

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. If you have a single-writer scenario, see AbsorbConditionalErrorsOnRetry to determine whether setting this flag to true is acceptable for your scenario.
