    You do not have semi-colons in the first two statements. Is that a typo or the problem? If that is typo, then post the error message you get.

    It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD

            Actually the problem is DateTime parses according to the CultureSettings applied on the computer. If your global Date format is MM/dd/yyyy you cannot parse in dd/MM/yyyy. You can specify format while parse, using ParseExact function rather than Parse. :thumbsup:

                    use this

                    DateTime dt = DateTime.ParseExact("18/02/2001", "dd/MM/yyyy", new CultureInfo("en-US"));

                    You will get what you want. :cool:

                      Convert the string format date into Datetime format i.e. use the following code

                      DateTime dt = DateTime.ParseExact("25/11/2009", "dd/MM/yyyy", new CultureInfo("en-US"));

                      or u Can Use This

                      string ssd = DateTime.Now.AddDays(-1).ToString();
                      DateTime asd = Convert.ToDateTime(ssd);
                      ssd = asd.AddDays(-1).ToString();

                      if this is not Your Answer I am Sorry..!

                        you can do by this, just remove the opening and closing brace. string newdate =DateTime.Parse(todate).AddDays(-1).ToString("dd/MM/yyyy");
