title: Converting country codes in .NET
body: <p>In .NET is there any way to convert from three letter country codes (defined in ISO 3166-1 alpha-3) to two letter language codes (defined in ISO 3166-1 alpha-2)  eg. convert BEL to BE? </p>
  
  <p>Have looked at the RegionInfo class in System.Globalization but the constructor does not seem to support the three letter codes. </p>
