Answer 1

SQLException has Number property, you can use this number then translate to whatever text you want.

public static string GetSqlExceptionMessage(int number)
{
  //set default value which is the generic exception message
  string error = MyConfiguration.Texts.GetString(ExceptionKeys.DalExceptionOccured);   
  switch (number)
  {
    case 4060:
      // Invalid Database
      error = MyConfiguration.Texts.GetString(ExceptionKeys.DalFailedToConnectToTheDB);   
    break;
    case 18456:
      // Login Failed
      error = MyConfiguration.Texts.GetString(ExceptionKeys.DalFailedToLogin);   
    break;
    case 547:
      // ForeignKey Violation
      error = MyConfiguration.Texts.GetString(ExceptionKeys.DalFKViolation);   
    break;
    case 2627:
      // Unique Index/Constriant Violation
      error = MyConfiguration.Texts.GetString(ExceptionKeys.DalUniqueConstraintViolation);
    break;
    case 2601:
      // Unique Index/Constriant Violation
      error =MyConfiguration.Texts.GetString(ExceptionKeys.DalUniqueConstraintViolation);   
    break;
    default:
      // throw a general DAL Exception
      MyConfiguration.Texts.GetString(ExceptionKeys.DalExceptionOccured);   
    break;
  }

  return error;
}
