从描述属性获取枚举[重复]

public static class EnumEx{    public static T GetValueFromDescription<T>(string description)    {        var type = typeof(T);        if(!type.IsEnum) throw new InvalidOperationException();        foreach(var field in type.GetFields())        { var attribute = Attribute.GetCustomAttribute(field,     typeof(DescriptionAttribute)) as DescriptionAttribute; if(attribute != null) {     if(attribute.Description == description)         return (T)field.GetValue(null); } else {     if(field.Name == description)         return (T)field.GetValue(null); }        }        throw new ArgumentException("Not found.", nameof(description));        // or return default(T);    }}

用法：

var panda = EnumEx.GetValueFromDescription<Animal>("Giant Panda");
