初级图像问题

Question

小弟我新学C#,要在pictureBox里画一个五子棋棋盘和一些棋子.imgBoard = new Bitmap("..\\..\\board.bmp");//盘的位图
imgBlack = new Bitmap("..\\..\\black.bmp");//黑子
imgWhite = new Bitmap("..\\..\\white.bmp");//白子,这些都在资源里img = pictureBox1.CreateGraphics();
img.DrawImage (imgBoard,0,0,imgBoard.Width,imgBoard.Height);

for (int i=0;i<=14;i++)
{
for(int j=0;j<=14;j++)
{
if(game.getChess (i,j)==1)img.DrawImage(imgBlack,i*30+45,j*30+45,imgBlack.Width ,imgBlack.Height);//画黑子
if(game.getChess (i,j)==-1)img.DrawImage(imgWhite,i*30+45,j*30+45,imgWhite.Width ,imgWhite.Height);//画白子
}
}当我把这些代码写在form1_paint()里的时候,图像被遮挡后,就不能还原了.我又在后面加上
this.Invalidate();又发现闪的非常非常厉害.C#里的paint事件,跟C++里OnPaint事件的差别很大么?如何能解决这个问题呢?新手我是,拜谢了m(_ _)m

这个代码是在网上看了很多遍的,因为实在没明白,还是请大虾给指导一下吧...关键的在什么地方啊?
关于DGI+的部分,再谢....
