Parameters

fileTransfer

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

endpointDescriptor

Endpoint descriptor. Identifies the OPC-UA server.

fileNamedNodeDescriptor

The named node descriptor of the file on which the text file writer should be opened.

append

Specifies whether to append the text to the file.

Return Value

The OPC UA file must already exist for this method to succeed.

CAUTION: This method does not throw the usual OpcLabs.EasyOpc.UA.OperationModel.UAException. Instead, an System.IO.IOException is thrown in case of an error during the operation.

See OPC UA File Transfer internals for information about Stream buffering.

Recommendation: Whenever possible, do not use this method directly, and use a higher-level abstraction instead. You can obtain a writable file provider (using GetWritableFileProvider), and make use of its methods, and methods available on the writable directory contents (obtained using OpcLabs.BaseLib.Extensions.FileProviders.IWritableDirectory.GetWritableDirectoryContents) or writable file info (obtained using OpcLabs.BaseLib.Extensions.FileProviders.IWritableDirectory.GetWritableFileInfo).
