老是报} expected，哭了，明明已经和老师写的一模一样了

using System;
using System.Text;
namespace 面向对象编程_类
{
    public class Customer
    {
        public Customer()
        {
            public string name;
            public string address;
            public int age;
            public string buyTime;

            public void Show()
            {
                Console.WriteLine("名字"+name);
                Console.WriteLine("年龄"+age);
                Console.WriteLine("地址"+address);
                Console.WriteLine("购买时间"+buyTime);


            }


        }
    }
}
1. 

用折半查找法，每次用/*...*/注释掉一半，最终你会定位编译出错的具体位置。

把你的代码放到构造函数外面去

namespace 面向对象编程_类
{
    public class Customer
    {
        public Customer()
        {}
            public string name;
            public string address;
            public int age;
            public string buyTime;
 
            public void Show()
            {
                Console.WriteLine("名字"+name);
                Console.WriteLine("年龄"+age);
                Console.WriteLine("地址"+address);
                Console.WriteLine("购买时间"+buyTime);
            }
    }
}

你再给个 跟你老师的绝对不一样啊 你在好好看看
