Try this: using System; class MyClass { string numericString = 0; // default value public string NumericString { get { return numericString; } set { double number; bool isValid = double.TryParse(value out number); if (isValid) numericString = number.ToString(); else throw new ArgumentException(String.Format('{0}' is not a numeric string value)); } } } class Program { static void Main() { MyClass mc = new MyClass(); try { mc.NumericString = 12.34; mc.NumericString = abc; } catch(ArgumentException ex) { Console.WriteLine(ex.Message); } Console.ReadKey(); } }
