在下有个课设，用C#绘制中国象棋棋盘，在窗体上或者PICTURE BOX控件上绘制象棋棋盘，要求。程序运行后，如

private void Form1_Paint(object sender, PaintEventArgs e)
{
Pen blackPen = new Pen(Color.Black);
Pen blackWidePen = new Pen(Color.Black,3);
Pen blackWidePen2 = new Pen(Color.Black, 2);
for(int i =90; i < 440 ;i += 50)
{
e.Graphics.DrawLine(blackPen, i, 40, i, 240);
}
for (int i = 90; i < 440; i += 50)
{
e.Graphics.DrawLine(blackPen, i, 290, i, 490);
}
for (int i = 90; i < 490; i += 50)
{
e.Graphics.DrawLine(blackPen, 40, i, 440, i);
}
e.Graphics.DrawLine(blackWidePen, 39, 39, 441, 39);
e.Graphics.DrawLine(blackWidePen, 39, 491, 441, 491);
e.Graphics.DrawLine(blackWidePen, 40, 40, 40, 491);
e.Graphics.DrawLine(blackWidePen, 439, 40, 439, 492);
e.Graphics.DrawLine(blackPen, 190, 40, 290, 140);
e.Graphics.DrawLine(blackPen, 290, 40, 190, 140);
e.Graphics.DrawLine(blackPen, 190, 390, 290, 490);
e.Graphics.DrawLine(blackPen, 290, 390, 190, 490);
}
