善用=>匿名委託符

在新版本的ＩＬ編譯器整合了=>簡化的匿名委託的定義，這樣我們使用起來就更方便．
由於是編譯器支援所以能在vs2008裡編寫2.0應用程式使用這特性．    class Program
    {
        static void Main(string[] args)
        {

            Timing(() => {
                string i = "k";
            });
        }
   
        public delegate void EventDoing();
        public static void Timing(EventDoing e)
        {       
            System.Diagnostics.Stopwatch sw = new System.Diagnostics.Stopwatch();
            sw.Reset();
            sw.Start();
            e();
            sw.Stop();
            Console.WriteLine("總耗時:" + sw.Elapsed.TotalMilliseconds+"/毫秒");
        }
      
    }

DBRegion.Using<PostsMapper, PostCategories>(
                (p, pc) => {
                    (p.PostID == "test").Delete<Posts>();
                    (p.CreateDate >= DateTime.Parse("2008-1-1") & p.CreateDate <= DateTime.Now).List<Posts>();
                    (p.Summary == "test").Edit<Posts>(
                        p.Title.Set("title"),
                        p.Content.Set("bbq"));
                
            });
