類Ruby的loop

public static class LoopingExtensions { public static void Times(this int upperBound, Action action) { for (int index = 0; index < upperBound; index++) action.Invoke(index); } 用法: public static void TestRubyLoop(){ 50.Times(i => { Console.WriteLine("We Built This City..."); Console.WriteLine("We Built This City..."); Console.WriteLine("On Rock And Roll"); } }
