学习笔记取得枚举项的2种方法: Enum.GetValues()Array.GetValue()和Enum.GetNames()Enum.Parse()

namespace EnumDemo
{
    public enum Color
    {
        red = 0, orange =1, yellow =2, green=4, blue =5, cyan =6, purple = 7
    }

    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("------Enume.GetValues获得枚举项的数组(基类)-----");
            Array ary = Enum.GetValues(typeof(Color));  //array是数组的基类, 无法实例化
            foreach (int i in ary)  //列出枚举项对应的数字
            {
                Console.WriteLine(i.ToString());
            }
            Console.WriteLine("------------------------------------------------");
            foreach (Color c in ary)    //列出枚举项的枚举值
            {
                Console.WriteLine(c.ToString());
            }

            Console.WriteLine("------ary.GetValue获得枚举项-----");
            //Enumes.GetValues和ary.GetValue获得枚举项
            for (int i = 0; i < ary.Length; i++)
            {
                Console.WriteLine(ary.GetValue(i).ToString());  //可以通过(Color)ary.GetValue(i)获得枚举项的值
            }
            Console.WriteLine("------Enume.GetName获得枚举项的字符串数组-----");
            //Enume.GetNames和Enum.Parse获得枚举项
            string[] strary = Enum.GetNames(typeof(Color));
            foreach(string s in strary)
            {
                Console.WriteLine(s);
            }
            Console.WriteLine("------num.Parse获得枚举项-----");
            for (int i = 0; i < strary.Length; i++)
            {
                Console.WriteLine(Enum.Parse(typeof(Color), strary[i]).ToString());
            }

        }
    }
}
