新人求助，c#中绘制的图形如何按合适比例呈现在picturebox控件中央？

[X_QUEST]

int iXA, iYA, iXB, iYB, iXP, iYP;

Graphics g = pictureBox1.CreateGraphics();
Point[] p = new Point[]
{
new Point(iXA,iYA),
new Point(iXB,iYB),
new Point(iXP,iYP)
};

g.DrawString("A", new Font("宋体 ", 10f), Brushes.Black, new Point(iXA, iYA));
g.DrawString("B", new Font("宋体 ", 10f), Brushes.Black, new Point(iXB, iYB));
g.DrawString("P", new Font("宋体 ", 10f), Brushes.Black, new Point(iXP, iYP));
g.DrawPolygon(Pens.Red,p);

g.Dispose();
//我想实现绘制三角形，然后按合适比例呈现在picturebox控件中央，请问这个代码该怎么修改合适？

试试把PictureBox.Stretch = Fill...
