- 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
A Task object that represents the asynchronous operation.
- Attributes
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.
