title: How to get the DescriptionAttribute value from an enum member
body: <p>I have a enum type</p>
  
  <pre><code>public enum DataType:int
      {   
          None = 0,
          [Description("A")]
          Alpha = 1,
          [Description("N")]
          Numeric,
          [Description("AN")]
          AlphaNumeric,
          [Description("D")]
          Date
      }
  </code></pre>
  
  <p>How do I retrieve the description attribute value of, say, Alpha.</p>
  
  <p>Eg(ideal) : <code>DataType.Alpha.Attribute</code> should give <strong>"A"</strong></p>
