EnumDataTypeAttribute Class

This class lets you map the underlying value in a column to a corresponding enumeration constant name. This lets you define an enumeration that contains descriptive values that correspond to database values, and then use the enumeration constant names instead of the database values when data is displayed.

The following example shows how to replace the numeric value of an enumeration with the corresponding declaration.

public enum eReorderLvl {
        zero = 0,
        five = 5,
        ten=10,
        fifteen=15,
        twenty=20,
        twenty_five=25,
        thirty=30
    }
    [MetadataType(typeof(Product_MD))]
    public partial class Product {
        public class Product_MD {
            [EnumDataType(typeof(eReorderLvl))]
            public object ReorderLevel { get; set; }
        }
    }
