I\'m making a call:

myResult = MakeMyCall(inputParams, out messages);

but I don\'t actually care about the messages. If it was an input pa

Answer 1

If the original function is declared like this:

class C
{
    public Result MakeMyCall(Object arg, out List messages);
}

You can declare an extension method like this:

static class CExtension
{
    public static Result MakeMyCall(this C obj, Object arg)
    {
        List unused;
        return obj.MakeMyCall(arg, out unused);
    }
}

The extension method will behave like an overload that makes the out parameter optional.
