方法里获取外界变量名和值;

        public static int _成功订单个数 = 111;        private void test(Expression<Func<int,int>> exp)        {            //这里可以获取_成功订单个数的值111吗?            var body = exp.Body as MemberExpression;            Console.WriteLine("参数名：" + body.Member.Name);//_成功订单个数            Console.WriteLine("参数值:" + exp.Compile()(0));//111        }        private void buttonLogin_Click(object sender, EventArgs e)        {            test(p=>_成功订单个数);        }
