Parameters

fileTransfer

The OPC UA file transfer object that will perform the operation.

endpointDescriptor

Endpoint descriptor. Identifies the OPC-UA server.

directoryNodeDescriptor

Node descriptor of the OPC UA directory.

Return Value

The directoryNodeDescriptor must be an existing node in the server, of object type OpcLabs.EasyOpc.UA.AddressSpace.Standard.UAObjectTypeIds.FileDirectoryType.

Recommendation: Whenever possible, do not use this method directly, and use a higher-level abstraction instead. See e.g. the GetDirectoryContents2(IEasyUAFileTransfer,UAEndpointDescriptor,UANamedNodePath) method, which allows you to obtain an object that can be enumerated for files and directories underneath, in a way that is generic and not tied to OPC UA specifics.
