Use Double.TryParse or DateTime.TryParse.

Hi, Use the try catch block ! try { DateTime.Parse(textBox1.Text) // code if it is date ! } catch(Exception ex) { //error code }

There is a DateTime.TryParse method! It's new with the Framework 2.0 but as you found double.TryParse you're clearly using this version. Maybe you misspelled.

You don't know which .NET version you are using? Huh? Well if you can't use it, then you have .NET 1.1, otherwise .NET 2.0. But you can also use DateTime.Parse() and catch the exception regards
