Parameters

source
Uri

Specifies the Uri of the source blob. The value may be a Uri of up to 2 KB in length that specifies a blob. A source blob in the same storage account can be authenticated via Shared Key. However, if the source is a blob in another account, the source blob must either be public or must be authenticated via a shared access signature. If the source blob is public, no authentication is required to perform the copy operation.

The source object may be a file in the Azure File service. If the source object is a file that is to be copied to a blob, then the source file must be authenticated using a shared access signature, whether it resides in the same account or in a different account.

options
BlobCopyFromUriOptions

Optional parameters.

cancellationToken
CancellationToken

Optional CancellationToken to propagate notifications that the operation should be cancelled.

Returns

CopyFromUriOperation

A CopyFromUriOperation describing the state of the copy operation.
