以下三种写法都可以获取以a打头的字符串

            string[] arr = {"abc", "ass", "cc", "ef", "tta", "awee"};            //写法一            //var selected = arr.Where((s) => { return s.StartsWith("a"); });            //写法二            //var selected = arr.Where((s) => s.StartsWith("a"));            //写法三            var selected = from s in arr where s.StartsWith("a") select s;            foreach (var VARIABLE in selected)            {                System.Console.WriteLine(VARIABLE);            }
