So your problem is in how to run a task every 5 minutes. Use Timers: 

var timer = new System.Timers.Timer(TimeSpan.FromMinutes(5).TotalMilliseconds);

timer.Elapsed += Timer_Elapsed;
timer.Start();

private static void Timer_Elapsed(object sender, ElapsedEventArgs e)
{
    // call the function that takes the screenshot
}

  • timer.Elapsed += Timer_Elapsed;......... it does not call to Timer_Elapsed(object sender, ElapsedEventArgs e)..........I'm calling it like this: var timer = new System.Timers.Timer(TimeSpan.FromSeconds(2).TotalMilliseconds); timer.Elapsed += Timer_Elapsed; – Muneeb Ur Rehman Jul 14 '16 at 09:08
  • @muneeb sorry you need to use `timer.Start();` – Zein Makki Jul 14 '16 at 09:09
  • Thanks its done.......var aTimer = new System.Timers.Timer(1000); aTimer.Elapsed += new ElapsedEventHandler(Timer_Elapsed); aTimer.Interval = 1000; aTimer.Enabled = true;......... this code solved my problem.....really thanks to you also :) – Muneeb Ur Rehman Jul 14 '16 at 09:21

use this function to capture screen:

private static Image CaptureScreen()
    {
        Rectangle screenSize = Screen.PrimaryScreen.Bounds;
        var target = new Bitmap(screenSize.Width, screenSize.Height);
        using (Graphics g = Graphics.FromImage(target))
        {
            g.CopyFromScreen(0, 0, 0, 0, new Size(screenSize.Width, screenSize.Height));
        }
        return target;
    }

Saving to file:

var currentImage = CaptureScreen();
currentImage.Save(Path.Combine("Your directory path", "Your file name"));

Are you creating a new file name each time you save the image, meaning, instead of:

image.Save(@"D:\documents\FYP\snippetsource.jpg", ImageFormat.Jpeg);

Do something like:

image.Save(string.Format(@"D:\documents\FYP\snippetsource_{0}.jpg", Guid.NewGuid()), ImageFormat.Jpeg);

You can change Guid.NewCuid() with whatever unique string that makes more sense to your application.

Hope it helps!

  • Thanks its helpful.......var currentImage = ScreenCapture.CaptureScreen(); //currentImage.Save(Path.Combine(@"D:\documents\FYP", "abc.jpg")); currentImage.Save(string.Format(@"dll\snippetsource_{0}.jpg", Guid.NewGuid()), ImageFormat.Jpeg);............when I'm calling Time_Elapsed it does not work............I'm calling it like this: private void timer1_Tick(object sender, EventArgs e) { var timer = new System.Timers.Timer(TimeSpan.FromSeconds(2).TotalMilliseconds); timer.Elapsed += Timer_Elapsed; } – Muneeb Ur Rehman Jul 14 '16 at 07:28
  • Try storing the created timer instance in a class level private memeber instead of a local method variable. – Itay Podhajcer Jul 14 '16 at 07:34
