public void Send(
The parameter name recipients implies that it is possible to send the email to more than one recipient - but the documentation does not say how. I tried separating the addresses with a semicolon, but that failed with the following error:
"Send" with "4" argument(s): "An invalid character was found in the mail header: ';'."The correct separator to use, which I only found out by trawling through the .NET source with ILSpy, is a comma (,).
