在C#中使用枚举时进行强制转换 [英] Casting while using enumerations in C#

问题描述

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

namespace ConsoleApplication1
{
       class Values
    {
        enum Temperatures
        {
            WickedCold=0,
            FreezingPoint=32,
            LightJacketWeather=60,
            SwimingWeather=72,
            BoilingPoint=212,
        }

        static void Main()
        {
            Console.WriteLine("Freezing Point of Water: {0}", (int)  Temperatures.FreezingPoint);
            Console.WriteLine("Boiling Point of Water: {0}", (int) Temperatures.BoilingPoint);
            Console.ReadLine();
        }
    }
}

我最近开始学习C#，但是我陷入了枚举的概念，即为什么默认情况下枚举是整数类型，为什么我们在显示输出时进行转换?
如果我删除(int)，则输出为冻结水":FreezingPoint?请帮助

I have recently started learning C# i am stucked in the concept of enumeration that why we are casting when displaying the output although enumeration by default is of type integer?
If i remove (int) the output is Freezing of water is: FreezingPoint? Please help

推荐答案

枚举的默认输出使用枚举的ToString方法.您需要将一个emum强制转换为int，以使输出格式化程序知道您想要输出的int版本.

The default output for an enum uses the ToString method of an enum. You need to cast an emum to int to let the output formatter know that you want the int version of output.
