How to get Difference between two dates? Lets see how to do it using [C#] and Vb.net.
We will use Time Span to get difference.

[C#] program to get Difference between two dates

C#.net program uses Time Span to get difference between From date and To Date.

using System;
namespace DateAndTime.Examples
{
class Program
{
static void Main(string[] args)
{
DateTime fromdate = DateTime.Parse("12/31/2011");
DateTime todate = DateTime.Parse("01/02/2012");
TimeSpan difference = todate.Subtract(fromdate);
Console.WriteLine(difference);
Console.ReadLine();
}
}
}

VB.net program to get difference between two dates

VB.net example of DateTime difference
Namespace DateAndTime.Examples
Class Program
Private Shared Sub Main(args As String())
Dim fromdate As DateTime = DateTime.Parse("12/31/2011")
Dim todate As DateTime = DateTime.Parse("01/02/2012")
Dim difference As TimeSpan = todate.Subtract(fromdate)
Console.WriteLine(difference)
Console.ReadLine()
End Sub
End Class
End Namespace

2.00:00:00 You can format this output using string formatters or Time Span formatters in C#.net or VB.net.
As There is only 2 day difference in given input dates, program output shows 2.

C#.net,VB.netDateTime Differance in days,hours,minutes and seconds

Using an instance of TimeSpan obtained by substracting two days, we can get differance in days, hours, minutes and seconds.

(C#.net) datetime differance example
using System;
namespace DateAndTime.Examples
{
class Program
{
static void Main(string[] args)
{
DateTime fromdate = DateTime.Parse("12/31/2011 12:10:15");
DateTime todate = DateTime.Parse("01/02/2012 10:03:13");
TimeSpan differance = todate.Subtract(fromdate);
Console.WriteLine("Total Time Span: {0} ", differance);
Console.WriteLine("Number of Days: {0} days.", differance.Days);
Console.WriteLine("Hours {0} ", differance.Hours);
Console.WriteLine("Minutes: {0}", differance.Minutes);
Console.WriteLine("Seconds: {0}", differance.Seconds);
Console.ReadLine();
}
}
}
(VB.net) DAteTime differance example
Namespace DateAndTime.Examples
Class Program
Private Shared Sub Main(args As String())
Dim fromdate As DateTime = DateTime.Parse("12/31/2011 12:10:15")
Dim todate As DateTime = DateTime.Parse("01/02/2012 10:03:13")
Dim differance As TimeSpan = todate.Subtract(fromdate)
Console.WriteLine("Total Time Span: {0} ", differance)
Console.WriteLine("Number of Days: {0} days.", differance.Days)
Console.WriteLine("Hours {0} ", differance.Hours)
Console.WriteLine("Minutes: {0}", differance.Minutes)
Console.WriteLine("Seconds: {0}", differance.Seconds)
Console.ReadLine()
End Sub
End Class
End Namespace

Total Time Span: 1.21:52:58
Number of Days: 1 days.
Hours 21
Minutes: 52
Seconds: 58
