Picture Box 点击委托事件
请问点击PictureBox后为什么没有执行pictureBox1_Paint

private void pictureBox1_Paint(object sender, PaintEventArgs e)

{

    Graphics g = e.Graphics;

    string rdWords = GetRandomWords();

    Font font = new System.Drawing.Font("Consolas", 18, FontStyle.Bold);

    g.DrawString(rdWords, font, Brushes.Red, 5, 5);

}

private void pictureBox1_Click(object sender, EventArgs e)

{

    PictureBox pb = new PictureBox();

    pb.Paint += new PaintEventHandler(pictureBox1_Paint);

}

------解决方案--------------------
初始化窗口的时候
pictureBox1.Paint += new PaintEventHandler(pictureBox1_Paint); 
private void pictureBox1_Click(object sender, EventArgs e)
{     
    pictureBox1.Refresh();
}
