------解决方案--------------------private void button1_Click(object sender, EventArgs e) 
 { 
     Graphics vGraphics = Graphics.FromImage(pictureBox1.Image); 
     vGraphics.DrawLine(Pens.Blue, new Point(0, 0), new Point(100, 16)); 
     pictureBox1.Invalidate();   
     pictureBox1.Image.Save(@ "c:\temp\temp.bmp ");
