Hi

Here is the number only portion of the pattern.

return Regex.Replace(text, @"(?i)[^0-9]", string.Empty).Trim();

You can simply apply regular expression for numeric value only and put "NA" in or condition
private bool IsNumericOrNA(string str)
{
  if (Regex.IsMatch(str, "^\\d{1,10}$") || str =="NA")
    return true;
  else
    return false;    
}
