37 使用Lambda表达式代替方法和匿名方法

 

        static void Main(string[] args)
        {
            Func<int, int, int> add = (i, j) => { return i + j; };
            Action<string> print = (msg) => { Console.WriteLine(msg); };
            Predicate<int> a = (i) => { return i == 0; };
            print(add(1, 2).ToString());
            print(a(0).ToString());
            
        }
