stacked overflow problem med kode stump

Hejsa,

nogle der kan komme med et bud på hvorfor jeg ret ofte for stacked overflow exeption i denne kode.

jeg mener ikke den er i en uendelig løkke


  public static void Capture(Point SourcePoint, Point DestinationPoint, Rectangle SelectionRectangle, string FilePath)
        {
            bool tryAgain = false;
            int trymore = 0;
do
  {
  try
    {
using (Bitmap thisbitmap = new Bitmap(SelectionRectangle.Width, SelectionRectangle.Height))
{

  using (Graphics g = Graphics.FromImage(thisbitmap))
  {
  g.CopyFromScreen(SourcePoint, DestinationPoint, SelectionRectangle.Size);
    }

  string savePath = "C://temp/temp/123turn.bmp";
                   
                 
                 
  try
      {
  using (FileStream dstream = new FileStream(savePath, FileMode.Create))
{
  thisbitmap.Save(dstream, ImageFormat.Bmp);
    dstream.Close();
  }
  tryAgain = false;
    trymore = 0;
  }
catch
  {
  trymore = trymore + 1;
  if (trymore <= 1)

                             
  tryAgain = true;
else
  tryAgain = false;
                        }
                   
                }

            }

            catch
            {
            }
                    }
while (tryAgain);

        }
