枚举类型和 struct类型

C#的四种访问修饰符：
public
private
internal
protected：只有继承他的才能访问、

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Test
{
    //enum枚举类型
    enum days {Monday=1 ,Tuesday ,Wenesday, Thursday, Friday, Saturday ,Sunday };
    //强制转换为byte字节
    //enum days :byte { Monday = 1, Tuesday, Wenesday, Thursday, Friday, Saturday, Sunday };
    class Program
    {
        /// <summary>
        /// 
        /// </summary>
        /// <param name="args"></param>
        static void Main(string[] args)
        {
            int intValue = 1;
            int intValue2 = new int();

            bool a = true; //System.bool
            Boolean b = true; //System.Boolean
            Console.WriteLine("{0},{1}",a, b); //输出a，b

            Person person = new Person();
            person.age = 10;
            Console.WriteLine(person.age);

            var c = days.Monday;
            Console.WriteLine((int) c);   //输出c并强制转换为int类型
            //Console.WriteLine(days.Monday);
            Console.Read();

  
        }

        //struct类型：是来用打包和封装一个小的数据集
        struct Person
            {
                public int age;
                public string name;
                public string name1;

            }
    }
}
