C#简单的枚举及结构

using system;
namespace program
{
    enum weekdays
    {
        a,//0
        b,//1
        c = 11,//11 赋值以后就变成11，不赋值就是2
        d,//12
        e,//13
        f,//14
        g//15
    }//不能输入数字


    struct student {
        public string name;
        public char sex;
        public int age;
    }
    class program1
    {
        static void main(string[] args)
        {
            weekdays letter;
            letter = weekdays.e;
            for (letter = 0; letter < weekdays.g; letter++)
            {
                console.writeline(letter);//看看枚举里的值到底是多少
            }

            student bruce;//结构体的运用
            bruce.age = 18;
            bruce.name = "布鲁斯";
            bruce.sex = '男';
            student talyo;
            talyo.age = 19;
            talyo.name = "泰勒";
            talyo.sex = '女';
            console.writeline("姓名：{0}",bruce.name);
            console.writeline("年龄：{0}",bruce.age);
            console.writeline("性别：{0}",bruce.sex);
            console.writeline("姓名：{0}",talyo.name);
            console.writeline("年龄：{0}", talyo.age);
            console.writeline("性别：{0}", talyo.sex);
