Public Overridable Function WritePagesAsync (pageData As Stream, startOffset As Long, contentChecksum As Checksum, accessCondition As AccessCondition, options As BlobRequestOptions, operationContext As OperationContext, cancellationToken As CancellationToken) As Task

Parameters

pageData
Stream

A Stream object providing the page data.

startOffset
Int64

The offset at which to begin writing, in bytes. The offset must be a multiple of 512.

contentChecksum
Checksum

A hash value used to ensure transactional integrity. May be null or Checksum.None

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.

cancellationToken
CancellationToken

A CancellationToken to observe while waiting for a task to complete.

Returns

Task

A Task object that represents the asynchronous operation.

Attributes
DoesServiceRequestAttribute

Remarks

Clients may send the content checksum headers for a given operation as a means to ensure transactional integrity over the wire. The contentChecksum parameter permits clients who already have access to a pre-computed checksum value for a given byte range to provide it. If the BlobRequestOptions.UseTransactionalMd5 or BlobRequestOptions.UseTransactionalCrc64 properties are set to true and the corresponding content parameter is set to null, then the client library will calculate the checksum value internally.
