Subtracting dates in ASP.NET with C#

Question

I'm working on subtracting dates in a web form in visual studio 2012 using a begin and end date - I want to find the day difference.

I have two separate web forms that I have connected.

DateTime ArrivalDateCalc = Convert.ToDateTime(.Text)

is what I have tried to use, but it does not work.

Any clues or guidance?

Can you be more specific on "does not work"? Do you get an exception? Is the value wrong? — D Stanley, Oct 02 '15 at 03:33
Can you show your HTML? .Text in Convert.ToDateTime(.Text) seems to be incorrect. — JGV, Oct 02 '15 at 03:33

You can use .Subtract to subtract dates in C#:

System.DateTime date1 = new System.DateTime(1996, 6, 3, 22, 15, 0);
System.DateTime date2 = new System.DateTime(1996, 12, 6, 13, 2, 0);

// diff1 gets 185 days, 14 hours, and 47 minutes.
System.TimeSpan diff1 = date2.Subtract(date1);

The result is TimeSpan, which you can get Day, Year etc from it..

You can Subtract two dates to find out the days difference.

string sdate = "2018-08-25";
string edate = "2018-08-23";

double days = (Convert.ToDateTime(sdate) - Convert.ToDateTime(edate)).TotalDays;
Response.Write("Difference = " + days);

Although the question is very unclear, but assuming you are using some format;

string startDateInText = "01/01/2014";
string endDateInText = "31/12/2014";
System.DateTime startDate = DateTime.ParseExact(startDateInText, "dd/MM/yyyy", System.Globalization.CultureInfo.CurrentCulture);
System.DateTime endDate = DateTime.ParseExact(endDateInText , "dd/MM/yyyy", System.Globalization.CultureInfo.CurrentCulture);

System.TimeSpan diff = endDate.Subtract(startDate);
//diff.Days will provide difference in Days`

You can directly use the "-" operator to get the difference.

e.g.

System.TimeSpan diff2 = date2 - date3;

You can use the Day property of timespan object to get the difference
