如何访问枚举值 [英] how to access enum values

问题描述

i面临访问枚举值的问题。



i制作枚举



enum caroptions

{

maruti alto，

swift lx，

xylo xuv

};

但是我在intellisense中的价值即将到来

for maruti alto只有maruti

并且swift lx只是很快。



所有值在空间未来之后。



i am access比如按钮点击事件



caroptions option = option。（枚举中的值名称）



please帮助我。

Hi,
i am facing a problem to access enum values.

i made an enum

enum caroptions
{
maruti alto,
swift lx,
xylo xuv
};
but while i am acessing values in intellisense is coming
for maruti alto is only maruti
and swift lx is only swift.

for all values after space is not coming.

i am accessing like on button click event

caroptions option = option.(name of values inside enum)

please help me.

推荐答案

我相信你现在已经意识到，Enum标签不能使用空格，但是，有一种方法可以将描述性文本与每个空格相关联枚举元素：

As I am sure you realize by now, Enum labels cannot use white-space, but, there is a way you can associate descriptive text with each Enum element:

// requires: using System.ComponentModel;

enum caroptions
{
    [Description("maruti alto")]
    maruti,
    [Description("swift lx")]
    swift,
    [Description("xylo xuv")]
    xylo
}

但是，在运行时访问该描述性文本需要使用System.Reflection;你真的想要付出这样的代价：

However, accessing that descriptive text at run-time requires using System.Reflection; do you really want to be paying the price of using code like this:

FieldInfo fi = caroptions.maruti.GetType().GetField(caroptions.maruti.ToString());

string description = ((DescriptionAttribute[]) fi.GetCustomAttributes(typeof (DescriptionAttribute), false))[0].Description;

是的，当然你可以把这个代码打包在一个方法中，或者把它变成一个扩展方法，并减少它的冗长，但是你仍然在为一个小的回报做一些繁重的工作。

Yes, of course you could package that code up in a method, or make it into an extension method, and reduce its verbosity, but you are still doing some heavy-lifting, imho, for a small pay-off.

嗨试试这个

hi try this

enum caroptions
 {
 maruti_alto,
 swift_lx,
 xylo_xuv
 };

caroptions option = option.maruti_alto;

见MSDN [ ^ ]

不要在你的枚举中留出空间



参考这个： - [ ^ ]

don't give space in your enum
