获取枚举值的属性 [英] Getting attributes of Enum's value
本文介绍了获取枚举值的属性的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
使用System.ComponentModel; // for DescriptionAttribute
枚举FunkyAttributesEnum
{
[描述(Name with Spaces1)]
NameWithoutSpaces1,
[描述(Name with Spaces2 )]
NameWithoutSpaces2
}
我想要的是枚举类型,产生2元组的枚举字符串值及其描述。
价值很简单:
数组值= System.Enum.GetValues(typeof(FunkyAttributesEnum));
foreach(值中的值)
Tuple.Value = Enum.GetName(typeof(FunkyAttributesEnum),value);但是如何获取描述属性的值,以填充Tuple.Desc?
如果属性属于枚举本身,我可以想到如何做,但是我从枚举的值中得到它是如何得到的。
解决方案
这应该是你需要的。
var type = typeof(FunkyAttributesEnum);
var memInfo = type.GetMember(FunkyAttributesEnum.NameWithoutSpaces1.ToString());
var attributes = memInfo [0] .GetCustomAttributes(typeof(DescriptionAttribute),false);
var description =((DescriptionAttribute)attributes [0])。
I would like to know if it is possible to get attributes of the enum values and not of the enum itself? For example, suppose I have the following enum:
using System.ComponentModel; // for DescriptionAttribute
enum FunkyAttributesEnum
{
[Description("Name With Spaces1")]
NameWithoutSpaces1,
[Description("Name With Spaces2")]
NameWithoutSpaces2
}
What I want is given the enum type, produce 2-tuples of enum string value and its description.
Value was easy:
Array values = System.Enum.GetValues(typeof(FunkyAttributesEnum));
foreach (int value in values)
Tuple.Value = Enum.GetName(typeof(FunkyAttributesEnum), value);
But how do I get description attribute's value, to populate Tuple.Desc? I can think of how to do it if the Attribute belongs to the enum itself, but I am at a loss as to how to get it from the value of the enum.
解决方案
This should do what you need.
var type = typeof(FunkyAttributesEnum);
var memInfo = type.GetMember(FunkyAttributesEnum.NameWithoutSpaces1.ToString());
var attributes = memInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), false);
var description = ((DescriptionAttribute)attributes[0]).Description;
