    He could've written:

    if (Convert.ToChar(chkdate.Length.ToString().ToCharArray()[0]) != new String("1").ToCharArray()[0])
    {
    if (Convert.ToChar(chkdate.Length.ToString().ToCharArray()[1]) != new String("1").ToCharArray()[0])
    {
    return false;
    }

    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'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. :)

            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|

                                    Then even the lead developer would be shocking.

                                      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 can't not ONE of you folkes be grown up enough to simply say that the rubbish: ://it checks if it contains 11 char (dd/MMM/yyyy) if (Convert.ToInt16(chkdate.Length.ToString()) != 11) { // Do something if not. } SHOULD be: :// it checks if it contains 11 char (dd/MMM/yyyy) if (chkdate.Length != 11) { // Do something if not. } How hard can it be? It's OK to pinpoint bad code like that but it's not OK not to come up with a useable alternative.

                                        Shouldn't the comparison do this? :laugh: if (chkdate.Length.ToString() != "11")

                                          Michael, Is your sense of humor having a bad day? But if we are geting serious, I'd like to point out that your question contains a double negative and means the opposite of your apparent intended meaning.
