C#多枚舉值的寫法與讀法

標籤：

首先，定義枚舉的時候必須是2,4,8,16這種2的次方的值。

 

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace ConsoleApplication1{    public enum TestEnum { None = 1, Value1 = 2, Value2 = 4, Value3 = 8, Value4 = 16, Value5 = 32};    class Program    {        static void Main(string[] args)        {            TestEnum test;            //Detection            test = TestEnum.Value3 | TestEnum.Value4;            Console.WriteLine((test & TestEnum.Value2) == TestEnum.Value2);            //Remove            test = TestEnum.Value3 | TestEnum.Value4;            test &= ~TestEnum.Value3;            Console.WriteLine((test & TestEnum.Value3) == TestEnum.Value3);            Console.ReadLine();            //Print:            //false            //false        }    }}
