    I've just read an article that included this little gem

    ://it checks it contains 11 char (dd/MMM/yyyy) 
    if (Convert.ToInt16(chkdate.Length.ToString()) != 11) 
    { 
      //if it does not have 11 char then it will return false 
      return false; 
    }
    

    I really don't know where to start (and yes, chkdate is a string).

    why do you rely on an implicit Int16-to-Int32 conversion? I would recommend an explicit cast to make things more clear. :)

      That's right. You can't have enough casting and converting going on.

        Rediculous .. you need to convert both to decimal to guarentee precision and get rid of that pesky implicit conversion ...

        if(Convert.ToDecimal(Convert.ToInt16(chkdate.Length.ToString())) != Convert.ToDecimal("11")) {
        doNoRealValidationCheck_NeverLearnRegex();
        }


        I'm largely language agnostic


        After a while they all bug me :doh:

            Except you forgot to convert the char types to some int type to ensure it would be a numeric comparison. :rolleyes: :)

              Not so fast, your code does not work while his does. ;P [Hint] Your code will not return false for strings of length 1, 10, 101, etc.

                    I think this improves the code a lot… Extra precisions and conversions to make sure we're getting exactly what we want. :) ((Decimal)Convert.ToDecimal(chkdate.Length.ToString()) != (Decimal)Convert.ToDecimal(((Decimal)(11.0000000000000000000000000000)).ToString())).ToString() == Boolean.TrueString; The optimizing JITter is going to have fun with this one…

                      You left out the string.compare call with the ignore case option, and specifying the CultureInfo on the ToString calls. :doh:

                            For checking whether the string contains a valid date the code is crap. (SCNR) This shows what the results of "high level" programming languages are. X|

                                  It is now. It was removed because it was so bad and about the best comment against it was that it was complete and utter rubbish.

                                  Deja View - the feeling that you've seen this post before.

                                  It should have been 'An Article of Horror'. It is bad that it was removed and CP deprived many of a viewing pleasure. :mad:

                                    It worries me that we are spiralling into some kind of recursive software hellhole:

                                    void WritePoorCode()
                                    {
                                    bool stuck = true;

                                    if (stuck)
                                    {
                                        GetHelpFromAnotherMuppet();
                                    }
                                    

                                    }

                                    void GetHelpFromAnotherMuppet()
                                    {
                                    WritePoorCode();
                                    }

                                        Try it, you'll be surprised, and even more surprised if we see the same code being used in an Indian offshore system ;)
