Find bitmap on another bitmap and the position

Hello im begginer on C# and i have a bitmap with a image wich is updating every X seconds and i have another bitmap with a a model saved(As bitmap too), and i need to find on the main bitmap and get the [X, Y] on my screen where this bitmap is found on my main bitmap, im using a Windows Forms C#, i already searched about it, and i try this code, the first answer but i no understand nothing about this code i dont know how to use, i need a method with return of [X, Y] where is found this bitmap on my screen, here is a example what i need.

What im trying:

    private void Form1_Load(object sender, EventArgs e)      {          CurrentBtm = new Bitmap(600, 600);          searchbtm = new Bitmap(@"C:\Users\ghost\Desktop\TEST\tt.png");      }            private void Reader_Tick(object sender, EventArgs e)      {               CurrentBtm = CaptureScreen();              Point z = new Point();              var d = FindBitmap(CurrentBtm, searchbtm, out z);                Console.WriteLine(d);              Console.WriteLine(z);      }        public Point? Find(Bitmap haystack, Bitmap needle)      {          if (null == haystack || null == needle)          {              return null;          }          if (haystack.Width < needle.Width || haystack.Height < needle.Height)          {              return null;          }            var haystackArray = GetPixelArray(haystack);          var needleArray = GetPixelArray(needle);            foreach (var firstLineMatchPoint in FindMatch(haystackArray.Take(haystack.Height - needle.Height), needleArray[0]))          {              if (IsNeedlePresentAtLocation(haystackArray, needleArray, firstLineMatchPoint, 1))              {                  return firstLineMatchPoint;              }          }            return null;      }        private int[][] GetPixelArray(Bitmap bitmap)      {          var result = new int[bitmap.Height][];          var bitmapData = bitmap.LockBits(new Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadOnly,              PixelFormat.Format32bppArgb);            for (int y = 0; y < bitmap.Height; ++y)          {              result[y] = new int[bitmap.Width];              Marshal.Copy(bitmapData.Scan0 + y * bitmapData.Stride, result[y], 0, result[y].Length);          }            bitmap.UnlockBits(bitmapData);            return result;      }        private IEnumerable<Point> FindMatch(IEnumerable<int[]> haystackLines, int[] needleLine)      {          var y = 0;          foreach (var haystackLine in haystackLines)          {              for (int x = 0, n = haystackLine.Length - needleLine.Length; x < n; ++x)              {                  if (ContainSameElements(haystackLine, x, needleLine, 0, needleLine.Length))                  {                      yield return new Point(x, y);                  }              }              y += 1;          }      }        private bool ContainSameElements(int[] first, int firstStart, int[] second, int secondStart, int length)      {          for (int i = 0; i < length; ++i)          {              if (first[i + firstStart] != second[i + secondStart])              {                  return false;              }          }          return true;      }        private bool IsNeedlePresentAtLocation(int[][] haystack, int[][] needle, Point point, int alreadyVerified)      {          //we already know that "alreadyVerified" lines already match, so skip them          for (int y = alreadyVerified; y < needle.Length; ++y)          {              if (!ContainSameElements(haystack[y + point.Y], point.X, needle[y], 0, needle.Length))              {                  return false;              }          }          return true;      }   public Bitmap CaptureScreen()      {          //Creating a Rectangle object          Point recp = new Point(1318, 81);          Rectangle captureRectangle = new Rectangle(recp, CurrentBtm.Size);            //Creating a New Graphics Object          Graphics CaptureGraphics = Graphics.FromImage(CurrentBtm);            //Copying Image from The Screen          try          {              CaptureGraphics.CopyFromScreen(captureRectangle.Left, captureRectangle.Top, 0, 0, captureRectangle.Size);          }          catch (Exception e)          {              Console.WriteLine("Bitmap Exeption" + e);          }          //Return          return CurrentBtm;      }  

On my console even with the btm to found shows {x=0, Y=0} aways.
