C#4.0 新特性 泛型委托，Action，Func用法

//Action 无返回值 执行一个void方法

Action<string> myAction;

//Func 最后一个参数接受返回值
        Func<string, string> myFunc;


        Action<string> action = new Action<string>(delegate(string name)
        {
            MessageBox.Show("Hello" + name);
        });


        private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            myAction = TestAction;
            myAction("myAction");

            myFunc = TestFunc;
            var a = myFunc("myFunc");
            MessageBox.Show(myFunc.ToString());
        }

        void TestAction(string a)
        {
            MessageBox.Show(a);
        }

        string TestFunc(string a)
        {
            return a;
        }
