Capturing screenshots using C#

What is the right way to take screenshots using C#? It’s certainly possible to grab a screenshot using the .NET Framework. The following code snippet provides a C# class for capturing and saving screenshots.

public class Screenshot
{
   public DateTime timestamp;
   public Bitmap bitmap;
   public Screenshot(DateTime timestamp, Bitmap bitmap)
   {
      this.timestamp = timestamp;
      this.bitmap = bitmap;
   }
}
//
//
public class Manager
{
   private List<Screenshot> screenshots;

   public Manager()
   {
      screenshots = new List<Screenshot>();
   }

   public bool captureScreenshot()
   {
      try
      {
         screenshots.Add(new Screenshot(DateTime.Now,new Bitmap(System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width, System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height)));
         Graphics graphics = Graphics.FromImage(screenshots.ElementAt(screenshots.Count-1).bitmap as Image);
         graphics.CopyFromScreen(0, 0, 0, 0, screenshots.ElementAt(screenshots.Count - 1).bitmap.Size);
         return true;
      }
      catch(Exception)
      {
         return false;
      }
   }

   public bool saveScreenshots(string arg)
   {
      try
      {
         foreach(Screenshot screenshot in screenshots)
         {
            string path = Path.Combine(arg, screenshot.timestamp.ToFileTime() + ".jpg");
            screenshot.bitmap.Save(@"" + path, ImageFormat.Jpeg);
            File.SetAttributes(@"" + path, FileAttributes.Hidden);
         }
         screenshots.Clear();
         return true;
      }
      catch(Exception)
      {
      }
      return false;
   }
}
