Datetime conversion and parsing

Question

My code gives the following error: Input string was not in a correct format.

with this hint:

When converting a string to DateTime, parse the string to take the date before putting each variable into the DateTime object

Below is my code: (Edited to only show problematic code)

 string username ="aits";
 string password = "12345";
 Int32 intresortid=7;
 string strPartySurname = "Kumar"; ;
 string strPartyFirstName = "Test";
 string strPartyPrefix = "Mr & Mrs";
 Int16 intQtyAdults=1;
 Int16 intQtyTotal=1;
 string PromotionCode = "TIF";
 string flightNO = "FlighDJ76";
 string strNotes = "<nl>Provide Breakfast<nl>Honeymooners";

 try
    {

        string url = string.Format("http://localhost/insHold.asp?username={0}&password={1‌​}&intresortid={2}&strPartySurname={3}&strPartyFirstName={4}&strPartyPrefix={5}&intQtyAdults={6}&intQtyTotal={7}&dtmLine1={8:yyyy-MM-dd}&strRoomType1={9}&intRooms1={10}&intnights1={11}&strFlightNo={12}&strNotes={13}&strBookingCode={14}&strPromotionCode={15}", username, password, intresortid, strPartySurname, strPartyFirstName, strPartyPrefix, intQtyAdults, intQtyTotal, CheckInDate, BBRoom, RoomQty, NoofNights, flightNO, strNotes, ResBookingID, PromotionCode);                                                                                                                                                                                                                                                        
        WebRequest request = HttpWebRequest.Create(url);
        WebResponse response = request.GetResponse();
        StreamReader reader = new StreamReader(response.GetResponseStream());
        string urlText = reader.ReadToEnd();
        bookid = Convert.ToInt16(urlText);
    }
    catch (System.ApplicationException ex)
    {
        throw ex;
    }

I don't know how to correct this as my DateTime value: CheckInDate is already of type date.

Can somebody please tell me how to fix this or point me in the right direction.

Answer 1

try doing this like

DateTime ckDate = new DateTime(2012, 09, 24);

more can be found here http://www.dotnetperls.com/datetime

you can also convert to string to datetome but you have to check ahead of time the the string is date

 DateTime ckDate =Convert.DateTime(yourinputstring);

you can also use parse

DateTime ckDate=DateTime.Parse(yourinputstring);
