C# IsNumeric Function

  • I’m adding this to my code snippets since I use it a lot. It’s a function to check if an object is numeric in C#. It’s similar to the VB IsNumeric method.
     
    public static bool IsNumeric(object expression)
    {
        if (expression == null)
            return false;

        double number;
        return Double.TryParse(Convert.ToString(expression, CultureInfo.InvariantCulture), 
                System.Globalization.NumberStyles.Any, NumberFormatInfo.InvariantInfo, out number);
    }
