      I would not use Convert.ToDateTime with a text/string input. Instead try using TryParse with datetime. DateTime.TryParse Method (String, DateTime) (System)[^]

        Actually (to build on Slacker's answer), the return value of the TryParse method is either true or false, and if true, the specified out parameter contains the parsed DateTime value. If the return value is false, the specified string was not in a recognizable DateTime string format. Additionally, if you know for sure what the format of the string will be, you can use ParseExact. For details about using either of these methods, google is, once again, your friend.

            You can't set a DateTime to null. :)

                I don't think you would set a DateTime to string.empty.

                  Of course you can't. But I don't know how they are working with the actual data and displaying it. I am starting to regret posting an answer to his question. :sigh:

                    That's not what I would call a reasonable practice. I prefer my DateTimes to be valid in some way (and use new DateTime(0) to accomplish that).

                            Yes. Yes, I do. If I wasn't always an assh*le, I would disappoint my legions of fans. Besides, me being an assh*le is really the only constant in life any more that absolutely EVERYBODY can count on. Beyond that, I was just poking you in the ribs. If you're honestly butt-hurt, I can call a waaa-mbulance for you. :) BTW, I'm the one that voted your original answer a 5.

                              We can argue the validity of nulls all day. I don't like 'em, and I strive to resolve them in some way.

                                One would use a "shipped event", in that case. One could drop and smash the shipment .... One does not carry a null "damaged date" in anticipation.

                                    I would not use Convert.ToDateTime with a text/string input. Instead try using TryParse with datetime. DateTime.TryParse Method (String, DateTime) (System)[^]

                                        Read the whole thread - the answer is there.

                                        You can never have too much ammo - unless you're swimming, or on fire. - JSOP, 2010

                                        When you pry the gun from my cold dead hands, be careful - the barrel will be very hot. - JSOP, 2013
