在pictureBox中画方格矩阵地图，方法比较笨，有好方法望指导

用GDI+实现地图，在pictureBox1中绘制地图，代码如下：

public void Map()//绘制地图的函数

        {

            Graphics grapfics = pictureBox1.CreateGraphics();

            grapfics.Clear(Color.White);//清空并重置背景色

 

            Pen blackPen = new Pen(Color.Blue, 1);//边框颜色及线条粗细

            SolidBrush brush = new SolidBrush(Color.Black);//填充颜色

            for (i = 0; i < 300; i += 20)//点数及基本地图大小

            {

                for (j = 0; j <= 300; j += 20)

                {

                    Rectangle point = new Rectangle(i, j, 20, 20);//定位点的

                    grapfics.FillRectangle(brush, i, j, 20, 20);

                    grapfics.DrawRectangle(blackPen, point);//                    

                }

            }

        }
