Putting this here;

Rectangle[] myRectangle = new Rectangle[100];
for(int i = 0; i < 100; i++)
{
    myRectangle[i] = new Rectangle();
    myRectangle[i].Tag = i;
    myRectangle[i].MouseEnter += MouseEnter;
}
private void MouseEnter(object sender, MouseEventArgs e)
{
    Rectangle rect = (Rectangle)sender;
    int idx = (int)rect.Tag;
    MessageBox.Show(idx.ToString());
}
