Manual Profiler

using System;
using System.Diagnostics;
class MainClass 
{
  [STAThread]
  static void Main(string[] args)
  {
    DateTime Start = DateTime.Now;
    DateTime End = DateTime.Now;
    TimeSpan CallTime = End - Start;
    Console.WriteLine("Call Time(MS): " + CallTime.Milliseconds.ToString());
  }
}

Call Time(MS): 0

Measures the time taken to add some numbers

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);
  }
}

Milliseconds = 0
total = 499999500000

TimeSpan calculation

using System;
class MainClass
{
    public static void Main(string[] args)
    {
        TimeSpan timespan1 = new TimeSpan(2, 12, 0, 0);
        // Create a TimeSpan representing 4.5 days.
        TimeSpan timespan2 = new TimeSpan(4, 12, 0, 0);
        // Create a TimeSpan representing 1 week.
        TimeSpan oneWeek = timespan1 + timespan2;
        
        Console.WriteLine("oneWeek   : {0}", oneWeek);
    
    }
}

oneWeek   : 7.00:00:00

Use the Add() method to add a TimeSpan instance to another

using System;
class MainClas
{
  public static void Main()
  {
    TimeSpan myTimeSpan13 = new TimeSpan(1, 10, 13);
    TimeSpan myTimeSpan14 = new TimeSpan(2, 6, 10);
    TimeSpan myTimeSpan15 = myTimeSpan13.Add(myTimeSpan14);
    Console.WriteLine("myTimeSpan13 = " + myTimeSpan13);
    Console.WriteLine("myTimeSpan14 = " + myTimeSpan14);
    Console.WriteLine("myTimeSpan15 = " + myTimeSpan15);
  }
}

myTimeSpan13 = 01:10:13
myTimeSpan14 = 02:06:10
myTimeSpan15 = 03:16:23

Use the Add() method to add a TimeSpan to a DateTime

using System;
class MainClass
{
  public static void Main()
  {
    
    DateTime myDateTime = DateTime.Parse("1/11/2004 23:10:30");
    
    TimeSpan myTimeSpan = new TimeSpan(1, 2, 4, 10);
    DateTime myDateTime7 = myDateTime.Add(myTimeSpan);
    Console.WriteLine("myTimeSpan = " + myTimeSpan);
    Console.WriteLine("myDateTime6.Add(myTimeSpan) = " + myDateTime7);
  }
}

myTimeSpan = 1.02:04:10
myDateTime6.Add(myTimeSpan) = 03/11/2004 1:14:40 AM

Use the Duration() method to add two TimeSpan instances

using System;
class MainClas
{
  public static void Main()
  {
    TimeSpan myTimeSpan13 = new TimeSpan(1, 10, 13);
    TimeSpan myTimeSpan14 = new TimeSpan(2, 6, 10);
    TimeSpan myTimeSpan15 = myTimeSpan13.Subtract(myTimeSpan14);
    
    Console.WriteLine("myTimeSpan15.Duration() = " + myTimeSpan15.Duration());
  }
}

myTimeSpan15.Duration() = 00:55:57

Use the FromDays(), FromHours(), FromMinutes(), FromSeconds(), FromMilliseconds(), and FromTicks() methods to create new TimeSpan instances

using System;
class MainClas
{
  public static void Main()
  {
    TimeSpan myTimeSpan5 = TimeSpan.FromDays(5);
    Console.WriteLine("TimeSpan.FromDays(5) = " + myTimeSpan5);
    TimeSpan myTimeSpan6 = TimeSpan.FromHours(10);
    Console.WriteLine("TimeSpan.FromHours(10) = " + myTimeSpan6);
    TimeSpan myTimeSpan7 = TimeSpan.FromMinutes(30);
    Console.WriteLine("TimeSpan.FromMinutes(30) = " + myTimeSpan7);
    TimeSpan myTimeSpan8 = TimeSpan.FromSeconds(15);
    Console.WriteLine("TimeSpan.FromSeconds(15) = " + myTimeSpan8);
    TimeSpan myTimeSpan9 = TimeSpan.FromMilliseconds(200);
    Console.WriteLine("TimeSpan.FromMilliseconds(200) = " + myTimeSpan9);
    TimeSpan myTimeSpan10 = TimeSpan.FromTicks(500);
    Console.WriteLine("TimeSpan.FromTicks(500) = " + myTimeSpan10);
  }
}

TimeSpan.FromDays(5) = 5.00:00:00
TimeSpan.FromHours(10) = 10:00:00
TimeSpan.FromMinutes(30) = 00:30:00
TimeSpan.FromSeconds(15) = 00:00:15
TimeSpan.FromMilliseconds(200) = 00:00:00.2000000
TimeSpan.FromTicks(500) = 00:00:00.0000500

Use the Negate() method to add two TimeSpan instances

using System;
class MainClas
{
  public static void Main()
  {
    TimeSpan myTimeSpan13 = new TimeSpan(1, 10, 13);
    TimeSpan myTimeSpan14 = new TimeSpan(2, 6, 10);
    TimeSpan myTimeSpan15 = myTimeSpan13.Subtract(myTimeSpan14);
    
    
    Console.WriteLine("myTimeSpan15.Negate() = " + myTimeSpan15.Negate());
    Console.WriteLine("myTimeSpan14.Negate() = " + myTimeSpan14.Negate());

  }
}

myTimeSpan15.Negate() = 00:55:57
myTimeSpan14.Negate() = -02:06:10

Use the Subtract() method to subtract a TimeSpan from a DateTime

using System;
class MainClass
{
  public static void Main()
  {
    
    DateTime myDateTime = DateTime.Parse("1/11/2004 23:10:30");
    
    TimeSpan myTimeSpan = new TimeSpan(1, 2, 4, 10);
    DateTime myDateTime7 = myDateTime.Subtract(myTimeSpan);
    Console.WriteLine("myTimeSpan = " + myTimeSpan);
    Console.WriteLine("myDateTime6.Subtract(myTimeSpan) = " + myDateTime7);
  }
}

myTimeSpan = 1.02:04:10
myDateTime6.Subtract(myTimeSpan) = 31/10/2004 9:06:20 PM

Use the Subtract() method to subtract a TimeSpan instance from another

using System;
class MainClas
{
  public static void Main()
  {
    TimeSpan myTimeSpan13 = new TimeSpan(1, 10, 13);
    TimeSpan myTimeSpan14 = new TimeSpan(2, 6, 10);
    TimeSpan myTimeSpan15 = myTimeSpan13.Subtract(myTimeSpan14);
    Console.WriteLine("myTimeSpan15 = " + myTimeSpan15);
  }
}

myTimeSpan15 = -00:55:57
