我如何实现这个委托？
操作似乎不支持 params string[] 作为参数，所以我写了
delegate void WriteFn(string s, params string[] ls);
我有这个函数
void blah(WriteFn Write, string fmt, params string[] a)
现在我想编写一个函数，但我似乎无法弄清楚语法。类似于
{
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
我该如何写这个？
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?

你的问题不清楚。我们是否应该猜测
sw是一个StreamWriter？如果是这样，看起来这会起作用：Your question is not clear. Are we suppose to guess that
swis aStreamWriter? If so, it looks like this would work:我认为你不能这样做，因为根据MSDN。
I think you can't do this because variable argument lists is NOT compatible with anonymous methods, according to MSDN.
