Cute method for logging exceptions

Here is a cute method which returns a string composed of exception (and all its inner exceptions) message and stack trace:

public static String GetExceptionUberStackTrace(Exception e)
{
  if (null == e) throw new ArgumentException("Exception parameter shouldn't be null!");
  String result = "";

  do {
    result += String.Format("Message: {0}{1}", e.Message, Environment.NewLine);
    result += String.Format(
        "Stack trace: {0}{1}{2}", 
        Environment.NewLine, 
        e.StackTrace, 
        Environment.NewLine
    );

    e = e.InnerException;

    if (null != e)
    {
      result += String.Format("{0}Inner exception:{1}", 
          Environment.NewLine, Environment.NewLine);
    }
    else
    {
      break;
    }

  } while (true);

return result;
}
