    {
        Bitmap bitmapPictureBox1;
        Bitmap bitmapPictureBox2;
        public Form2()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {

            if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {

                pictureBox1.ImageLocation = openFileDialog1.FileName;

                bitmapPictureBox1 = new Bitmap(openFileDialog1.FileName);
            }

        }

        private void button2_Click(object sender, EventArgs e)
        {
            if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {

                pictureBox2.ImageLocation = openFileDialog1.FileName;

                bitmapPictureBox2 = new Bitmap(openFileDialog1.FileName);
            }

        }

        private void button3_Click(object sender, EventArgs e)
        {
            bool compare = ImageCompareString(bitmapPictureBox1,bitmapPictureBox2);
            if(compare==true)
            {
                MessageBox.Show("match");

            }
            else
            {
                MessageBox.Show("not");
            }
        }
        public static bool ImageCompareString(Bitmap firstImage, Bitmap secondImage)
    {
       MemoryStream ms = new MemoryStream();
        firstImage.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
        String firstBitmap = Convert.ToBase64String(ms.ToArray());
       ms.Position = 0;
   
       secondImage.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
        String secondBitmap = Convert.ToBase64String(ms.ToArray());
 
      if (firstBitmap.Equals(secondBitmap))
      {
         return true;
     }
