sourceFileName

String. Path and name of file to upload. Required.

address

String or Uri. URL, IP address, or URI of destination server. Required.

userName

String. User name to authenticate. Default is an empty string: "".

password

String. Password to authenticate. Default is an empty string: "".

showUI

Boolean. Whether to display progress of the operation. Default is False.

connectionTimeout

Int32. Timeout interval in milliseconds. Default is 100 seconds.

onUserCancel

UICancelOption. Action to be taken when the user clicks Cancel. Default is ThrowException.

networkCredentials

ICredentials. Credentials for authentication.

The following conditions may cause an exception:

If showUI is set to True, a dialog box shows the progress of the operation and includes a Cancel button that the user can click to cancel the operation. Because the dialog box is not modal, it does not block user input to other windows in the program.

If the server does not respond within the interval specified in connectionTimeout, the operation is cancelled and an exception is thrown.
