How do i implement this delegate?

Question

Action doesnt seem to support params string[] as a param so i wrote

delegate void WriteFn(string s, params string[] ls);

i have this function

void blah(WriteFn Write, string fmt, params string[] a)

Now i would like to write an function but i cant seem to figure the syntax out. It something like

{
    var sw = ...
    blah(new WriteFn(s, ls) { sw.write(s, ls); }, fmt, a);
    //not what i want to do but close enough. remember sw isnt a param in WriteFn

How do i write this?

The code inside the {} doesnt matter (pretend its blank). I cant get the codeblock as a param to work. — , Feb 24 '10 at 01:35

Your question is not clear. Are we suppose to guess that sw is a StreamWriter? If so, it looks like this would work:

blah((s, ls) => sw.Write(s, ls), fmt, a);

I think you can't do this because variable argument lists is NOT compatible with anonymous methods, according to MSDN.
