Parameters
- size
The size of the write operation, in bytes. The size must be a multiple of 512.
- accessCondition
An AccessCondition object that represents the access conditions for the blob. If
null, no condition is used.
- options
A BlobRequestOptions object that specifies additional options for the request.
- operationContext
An OperationContext object that represents the context for the current operation.
Return Value
A stream to be used for writing to the blob.Thread Safety
