pictureBox显示问题
请问 Bitmap myBitmap = new Bitmap(apfPath);
Graphics g = pBShowPicture.CreateGraphics();
//放大
Rectangle expansionRectangle = new Rectangle(400, 10, myBitmap.Width * 2, myBitmap.Height * 2);
g.DrawImage(myBitmap, expansionRectangle);
这些代码怎么不管用，是不是我没把绘完的图显示在pictureBox中， 如何显示？ 谢谢。
[解决办法]
Bitmap myBitmap = new Bitmap(@"C:\Users\SaeWind\Desktop\123\1.png");
private void pictureBox1_Paint(object sender, PaintEventArgs e)
{
Graphics g = e.Graphics;
//放大
Rectangle expansionRectangle = new Rectangle(10, 10, myBitmap.Width * 2, myBitmap.Height * 2);
g.DrawImage(myBitmap, expansionRectangle);
}
