How to: Determine the Span Between Two Dates
This example calculates the difference in days between two dates and constructs a TimeSpan value for that difference.
Example
DateTime oldDate = new DateTime(2002,7,15);
DateTime newDate = DateTime.Now;
// Difference in days, hours, and minutes.
TimeSpan ts = newDate - oldDate;
// Difference in days.
int differenceInDays = ts.Days;
System.Console.WriteLine("Difference in days: {0} ", differenceInDays);
System.Console.ReadLine();
Compiling the Code
Copy the code and paste it into the Main method of a console application.
