Question

I wanna do something like this:

List<string> list = new List<string>();
... put some data in it ...

list.CallActionForEachMatch(x=>x.StartsWith("a"), ()=> Console.WriteLine(x + " matches!"););

Syntax: CallActionForEachMatch(Criteria, Action)

How is this possible? 🙂

I wouldn’t; I’d just use:

foreach(var item in list.Where(x=>x.StartsWith("a"))) {
    Console.WriteLine(item + " matches!");
}

But you could use:

list.FindAll(x=>x.StartsWith("a"))
    .ForEach(item=>Console.WriteLine(item + " matches!"));
