五子棋游戏-1(绘制棋盘)

首先要有一个棋谱，棋谱采用围棋棋谱19*19的棋盘，棋盘绘制在PictureBox控件上。
public int Lines = 19;        //线条书
public int LineSpace = 30;    //线间距
public int Margin = 30 / 2;    //边距(线间距/2)
public PictureBox PicCtrl;    //棋盘容器控件
然后使用GDI+绘制棋盘
Bitmap bmp = new Bitmap(PicCtrl.Width, PicCtrl.Height);
Graphics g = Graphics.FromImage(bmp);
……
Pen linePen = new Pen(Color.Black, 1);//画线笔
//Lines条横线
for(int i = 0; i < Lines; i++) {
    Point start = new Point(Margin, i * LineSpace + Margin);
    Point end = new Point(start.X+(Lines-1)*LineSpace, start.Y);
    g.DrawLine(linePen, start, end);
}
//Lines条竖线
……
最后，设计UI界面，界面中央添加PictureBox控件，并计算好Form的大小
