Cut an Image into 9 pieces C# [duplicate]

Answer 1

First off, instead of using img1, img2... use an array with a size of 9. Then it's much easier to do this using a couple of loops like this:

var imgarray = new Image[9];
var img = Image.FromFile("media\\a.png");
for( int i = 0; i < 3; i++){
  for( int j = 0; j < 3; j++){
    var index = i*3+j;
    imgarray[index] = new Bitmap(104,104);
    var graphics = Graphics.FromImage(imgarray[index]);
    graphics.DrawImage( img, new Rectangle(0,0,104,104), new Rectangle(i*104, j*104,104,104), GraphicsUnit.Pixel);
    graphics.Dispose();
  }
}

Then you can fill your boxes like this:

pictureBox1.Image = imgarray[0];
pictureBox2.Image = imgarray[1];
