c# - 通过描述获取枚举值

Question

Possible Duplicate:
Get Enum from Description attribute

我有一个使用描述属性的枚举。我希望能够根据传入的字符串设置对象 -> 属性值。如果该字符串与枚举值描述之一匹配，则应选择该值。我是否可以在不使用冗长的 for 循环的情况下做到这一点？

public enum Rule
{
     ....
     [Description("New Seed")]
     Rule2 = 2,
     ....
}

我希望的是这样的

var object = new oject{ rule = Rule.Where(r=> r.description == rulestring)}

Answer 1

        Rule f;
        var type = typeof(Rule);
        foreach (var field in type.GetFields())
        {
            var attribute = Attribute.GetCustomAttribute(field,
                typeof(DescriptionAttribute)) as DescriptionAttribute;
            if (attribute != null)
            {
                if (attribute.Description == "description"){
                    f = (Rule)field.GetValue(null);
                break;}
            }
            else
            {
                if (field.Name == "description"){
                    f = (Rule)field.GetValue(null);
                break;}
            }
        }
