Question

HI im trying to create a simple reservation form in visual studio that takes an arrival date and departure date, gets the duration and works out the cost of stay by multipling duration by £115 heres my code (the error pops up on line that begins “int nights = dateDiff” and says “Timespan cannot convert to int) thanks in advance for any help:

        String arrival, departure;
        arrival = textBox1.Text;
        departure = textBox2.Text;

        DateTime aDate, dDate;
        aDate = new DateTime();
        aDate = DateTime.ParseExact(arrival, "dd/mm/yyyy", null);
        dDate = new DateTime();
        dDate = DateTime.ParseExact(arrival, "dd/mm/yyyy", null);

        TimeSpan dateDiff;
        dateDiff = dDate.Subtract(aDate);
        int nights = dateDiff;

        textBox3.Text = ("" + nights);
        textBox5.Text = ("£" + (nights * 115));

Answer 1

try

int nights = (int) dateDiff.TotalDays;

See MSDN. It might be helpful ro round (i.e. (int) Math.Round(dateDiff.TotalDays) – see here.
