The problem here is that if Formatter.Deserialize() fails, the

I have many constants, each recurring as per country and declared in class as below:

class CountryRequests
{
  public const string JAP_ABC="JAP_012686";
  public const string JAP_PQR="JAP_012457";

enum CountryRequests
{
  JAP_012686,
  JAP_012457
