How do i implement this delegate?

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?

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

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);
