IsNumebric

This method can be used in your application for checking the Numeric value.

 public static bool IsNumeric( object expression )
        {
            // Variable to collect the Return value of the TryParse method.
            bool isNumber;    
           
// Define variable to collect out parameter of the TryParse method. If the conversion fails, the out parameter is zero.
           double retNum;
           
            // The TryParse method converts a string in a specified style and culture-specific format to its double-precision floating point number equivalent.
            // The TryParse method does not generate an exception if the conversion fails. If the conversion passes, True is returned. If it does not, False is returned.
           
             isNumber = Double.TryParse( Convert.ToString( expression ) , System.Globalization.NumberStyles.Any , System.Globalization.NumberFormatInfo.InvariantInfo , out retNum );
            
          return isNumber;
        }
