- offset
- Int64
The byte offset in the source at which to begin retrieving content.
- count
- Int64
The number of bytes from the source to return, or null to return all bytes through the end of the blob.
- sourceContentChecksum
- Checksum
A hash value used to ensure transactional integrity. May be null or Checksum.None
- sourceAccessCondition
- AccessCondition
An AccessCondition object that represents the access conditions for the source blob. If null, no condition is used.
- destAccessCondition
- AccessCondition
An AccessCondition object that represents the access conditions for the destination blob. If null, no condition is used.
- options
- BlobRequestOptions
A BlobRequestOptions object that specifies additional options for the request. If null, default options are applied to the request.
- operationContext
- OperationContext
An OperationContext object that represents the context for the current operation.
Returns
The offset at which the block was appended.
- Attributes
Applies to
AppendBlock(Stream, Checksum, AccessCondition, BlobRequestOptions, OperationContext)
Commits a new block of data to the end of the blob.

- contentChecksum
- Checksum
An optional 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. If null, default options are applied to the request.
- operationContext
- OperationContext
An OperationContext object that represents the context for the current operation.
Returns
The offset at which the block was appended.
- 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.
Applies to
Azure SDK for .NET
