Multiple description attributes on emums

Question

C# 4.0

If i want to set description for enum i may use DescriptionAttribute form System.ComponentModel;

public enum EnumWithDescription
{
    [Description("EnumDescription1")]
    EE = 1,
    [Description("EnumDescription2")]
    PP
}

but if i need another specific description i may implement my specific attribute and extension method which will return this additional description. e.g:

public enum EnumWithDescription
{

    [MyDescritption("MyDescription1")]
    [Description("EnumDescription1")]
    EE = 1
}

anumValue.MyExtensionMethod(); // return me MyDescritpion stirng value

may be there is some another more simple ways of doing this?

Answer 1

You may extend DescriptionAttribute like this:

class ExtraDescriptionAttribute : DescriptionAttribute
    {
        private string extraInfo;
        public string ExtraInfo { get { return extraInfo; } set { extraInfo = value; } }

        public ExtraDescriptionAttribute(string description)
        {
            this.DescriptionValue = description;
            this.extraInfo = "";
        }
    }
