Does C# support variable arguments (vararg's) on methods?

Oh great, here come the people complaining about a completely open ended interface... I can just hear the thunder now.

TIDAL WAVE!

That example seems like a bad idea.

I try to only use params to pass a variable number of the same things. In fact it is mostly strings.
To pass an array of object where the objects will be of arbitrary types is going to a dangerous place.

I wonder why vararg mode is so slow than pass by array ?

public class EntryPoint
{
[DllImport("msvcrt.dll", CharSet=CharSet.Ansi, CallingConvention=CallingConvention.Cdecl)]
extern static int printf(string format, __arglist);

public static void Main(String[] args)
{
printf("%s %d", __arglist("Flier Lu", 1024));
}
}

btw: Here is some articls from my blog about vararg mode.
