How to pass more than 2 parameters in C#

[dondigitech LaPel]

Sorry about the code being hard to read, but I can assure you that it
did not look like that when I copied and pasted the message. I'm a
hardware engineer
who has only been using c# for a couple weeks now and must admit that
its been a long time since I've done any OO programming. But, all I want
to do is when the "Get Curves" button is clicked, for the event handler
to call the initializeIgnComm grabbing int[,] curveArray from my
CurveData class, and then use that data to plot. Thats all I want this
event handler to do. Get data, then plot it. Before messing with
delegates and event handlers and all
that this how I had my code. Of course I got the overloading error.
Ultimately the issue I am having is getting/passing the curveArray data
to the event handler.

return;
}
else

PortSettings settings = new PortSettings();
if (settings.ShowDialog() == DialogResult.OK)

serialPort1.PortName = settings.selectedPort;

I'm going to reply in the original thread. Do NOT start multiple threads for
the same question. The regulars that are most likely to help you are also
very likely to be put off by this bad Netiquette.
