is this what you mean ? public static bool CheckForNumeric (string stringtocheck) { for (int i=0; i { if (char.isNumber(stringtocheck[i])) return true; } return false; } this will return true if there is a number in the string... if you want to check if a string is fully numeric then : public static bool IsNumeric ( string stringtocheck) { try { double number = double .Parse(stringtocheck); return true ; } catch { return false ; } }
