c# 关于枚举的反射运用

1.遍历枚举

1.1代码

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

namespace ConsoleApp1
{
    class Program
    {
        enum Sts { 
            状态1=0,
            状态2=1
        }
        static void Main(string[] args)
        {
            Console.WriteLine("枚举实验");
            //Array ar = Enum.GetValues(typeof(Sts));

            Program program = new Program();
            program.main();
            Console.ReadKey();
        }
        public void main() {
            遍历枚举();
        }

        private void 遍历枚举() {
            foreach (var a in Enum.GetValues(typeof(Sts)))
            {
                System.Console.WriteLine(a.ToString());
            }
        }
    }
}

2.枚举反射

2.1 代码

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

namespace ConsoleApp1
{
    class Program
    {
        enum Sts { 
            状态1=0,
            状态2=1
        }
        static void Main(string[] args)
        {
            Console.WriteLine("枚举实验");
            //Array ar = Enum.GetValues(typeof(Sts));

            Program program = new Program();
            program.main();
            Console.ReadKey();
        }
        public void main() {
            枚举反射();
        }

        private void 枚举反射() {
            Sts st1 = Sts.状态2;
            Console.WriteLine(st1.ToString());
            Console.WriteLine(st1.GetHashCode());
        }
    }
}

3.根据字符串获得枚举对象对应的值

3.1 代码

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

namespace ConsoleApp1
{
    class Program
    {
        enum Sts { 
            状态1=0,
            状态2=1
        }
        static void Main(string[] args)
        {
            Console.WriteLine("枚举实验");
            //Array ar = Enum.GetValues(typeof(Sts));

            Program program = new Program();
            program.main();
            Console.ReadKey();
        }
        public void main() {
            根据字符串获得枚举对象对应的值();
        }
        private void 根据字符串获得枚举对象对应的值() {
            Sts st2 = (Sts)Enum.Parse(typeof(Sts), "状态2");
            Console.WriteLine(st2);
            int a = (int)st2;
            Console.WriteLine(a);
        }
    }
}
