==Calculation based on the TimeSpan==

<source lang="csharp">
using System;
class Test
{
public static void Main()
{
// Create a TimeSpan representing 6.5 days.
TimeSpan timespan1 = new TimeSpan(6, 12, 0, 0);
// Create a TimeSpan representing 0.5 days.
TimeSpan timespan2 = new TimeSpan(0, 12, 0, 0);
TimeSpan oneWeek = timespan1 + timespan2;
DateTime now = DateTime.Now;
DateTime past = now - oneWeek;
// Create a DateTime representing 1 week in the future.
DateTime future = now + oneWeek;
// Display the DateTime instances.
Console.WriteLine("Now : {0}", now);
Console.WriteLine("Past : {0}", past);
Console.WriteLine("Future: {0}", future);
}
}

</source>

==Measuring the Time Taken to Add Some Numbers==

<source lang="csharp">
using System;
class MainClass {
public static void Main() {
DateTime start = DateTime.Now;
long total = 0;
for (int count = 0; count < 1000000; count++) {
total += count;
}
TimeSpan timeTaken = DateTime.Now - start;
Console.WriteLine("Milliseconds = " + timeTaken.Milliseconds);
Console.WriteLine("total = " + total);
}
}
</source>

==new TimeSpan( 0)==

<source lang="csharp">
using System;
class MainClass
{
public static void Main()
{
TimeSpan timespan1 = new TimeSpan(2, 12, 0, 0);
TimeSpan timespan2 = new TimeSpan(4, 12, 0, 0);
TimeSpan oneWeek = timespan1 + timespan2;
DateTime now = DateTime.Now;
DateTime past = now - oneWeek;
DateTime future = now + oneWeek;
Console.WriteLine("Now : {0}", now);
Console.WriteLine("Past : {0}", past);
Console.WriteLine("Future: {0}", future);
}
}
</source>

==Subtract 15 minutes from the current TimeSpan and print the result==

<source lang="csharp">
using System;
using System.Collections.Generic;
using System.Text;
class Program {
static void Main(string[] args) {
TimeSpan ts = new TimeSpan(4, 30, 0);
Console.WriteLine(ts);
Console.WriteLine(ts.Subtract(new TimeSpan(0, 15, 0)));
}
}
</source>

==TimeSpan.TicksPerDay==

<source lang="csharp">
using System;
using System.Globalization;
class MainClass {
public static void Main() {
// Create some date/time objects
DateTime dt = new DateTime();
DateTime dt1 = new DateTime(2001, 12, 31);
DateTime dt2 = new DateTime(2000, 12, 31, 23, 59, 59);
// Do some date time math
DateTime today = DateTime.Today;
today = today + new TimeSpan(TimeSpan.TicksPerDay);
Console.WriteLine("Tomorrow is: {0}", today.ToString());
today = DateTime.Today - new TimeSpan(7 * TimeSpan.TicksPerDay);
Console.WriteLine("Last Week on this day it was: {0}",today.ToString());
}
}
</source>
