as you may know c# is missing the nice and usfull IsNumeric function which is available in but it is a trivial task to implement a generic equvelant function for it. look at the following code. it will return true if the value is numeric and false if the value is false.

static bool IsNumeric(object value)


double retNum;return Double.TryParse(Convert.ToString(value), System.Globalization.NumberStyles.Any, System.Globalization.NumberFormatInfo.InvariantInfo, out retNum);
