Parameters
- uri
Type: System.Uri
The absolute URI to the destination blob.
- timeout
Type: System.Int32
The server timeout interval.
- source
Type: System.String
The canonical path to the source blob, in the form /<account-name>/<container-name>/<blob-name>.
- sourceSnapshot
Type: System.Nullable
The snapshot version, if the source blob is a snapshot.
- sourceConditions
Type: Microsoft.WindowsAzure.StorageClient.Protocol.ConditionHeaderKind
A type of condition to check on the source blob.
- sourceConditionsValue
Type: System.String
The value of the condition to check on the source blob.
- leaseId
Type: System.String
The lease ID for the source blob, if it has an active lease.
Return Value
Type: System.Net.HttpWebRequestA web request to use to perform the operation.Remarks
If the destination blob has an active lease, you must specify a valid lease ID for the active lease in order to copy the blob.
If the source blob has an active lease, you can optionally specify the lease ID for the source blob to copy the source blob conditionally. In this case, the source blob will be copied only if the lease ID for the source blob matches that specified on the request.
Copying a blob does not affect an existing lease on the destination blob. The destination blob's lease is maintained, whether you are copying a blob to a destination blob with a different name from the source, copying the blob to a destination blob with the same name as the source, or copying a snapshot over its base blob.
