Get Enum from Description attribute

I have an Enum that uses the descriptions attribute. I want to be able to set on objects -> property value based on a string passed in. If the string matches the one of the enum values description then that value should be chosen. Is it possible for me to this without using a lengthy for loop?

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

what I’m hoping for is something like

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

        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;}
            }
        }
