AE如何读取枚举属性值？

 public string GetDominValue(IFeature feature, int index)

        {

            var field = feature.Fields.Field[index];

            var domin = field.Domain;



            ICodedValueDomain codedValueDomain = domin as ICodedValueDomain;



            var key = int.Parse(feature.Value[index].ToString());



            var des = codedValueDomain.Name[key];



            return des.ToString();

        }
