OJ Problem 3490 C# teacher类

题目描述

定义一个教师类Teacher，具体要求如下： 

1、私有字段工号no（string）、姓名name（string）、出生日期birthday（DateTime）、性别sex（SexFlag）。其中，SexFlag为枚举类型，包括Male（表示男性）、Female（表示女性），并且字段sex缺省值为男。 

2、定义公有读写属性No用来访问no字段；定义公有读写属性Name用来访问name字段；定义公有只写属性Birthday用来赋值birthday字段；定义公有读写属性Sex用来访问sex字段。 

3、设计合理的构造函数，使得创建对象时可以设置工号、姓名、出生日期、性别。 

4、重写ToString()方法，用来输出Teacher对象的信息，具体格式如下描述。 

5、创建一个教师对象teacher（工号--0203, 姓名--zhangsan,出生日期--1987-12-09 , 性别--女)，调用ToString()方法后在控制台上显示teacher信息： 
根据以下代码，请补写缺失的代码。 

using System;
namespace ConsoleApplication1
{
    enum SexFlag
    {
        Male,Female
    }
    class Teacher
    {
        private string no;
        private string name;
        private DateTime birthday;
        private SexFlag sex = SexFlag.Male;
/

   //请填写代码

/
    }
    class Program
    {
        static void Main(string[] args)
        {
            Teacher teacher = new Teacher("0203", "zhangsan", DateTime.Parse("1987-12-09"), SexFlag.Female);
            Console.WriteLine(teacher.ToString());
        }
    }
}
