如何在picturebox上写入文字

Question

代码没有问题，是坐标位置超出了pictureBox的范围        public delegate void Paintp();
        public event Paintp p;
        protected override void OnPaint(PaintEventArgs e)//绿色
        {
            PointF pf = new PointF(0, 0);   //注意文字显示的坐标位置
            using (Graphics g = pictureBox1.CreateGraphics())
            {
                Font f = new Font("Arial", 12);
                g.DrawString("Hello!", f, Brushes.Green, pf);
            }
        }

            InitializeComponent();
        }        private void button1_Click(object sender, EventArgs e) //用按钮在pictureBox1内写字
        {
            Graphics g = pictureBox1.CreateGraphics();
            Brush ft=new  SolidBrush(Color.FromArgb(100, 200, 30));
            Point p=new Point (0,100);
            g.DrawString("在这里写字！",new Font ("宋体",20),ft,p );
        }        private void pictureBox1_Paint(object sender, PaintEventArgs e)
        {
            Graphics g = e.Graphics;
            Brush ft = new SolidBrush(Color.FromArgb(100, 200, 30));
            Point p = new Point(45, 45);
            g.DrawString("这是pictureBox1_Paint写字！", new Font("宋体", 20), ft, p);
        }        private void button2_Click(object sender, EventArgs e)
        {
            Graphics g = this.CreateGraphics();
            Brush ft = new SolidBrush(Color.FromArgb(100, 200, 30));
            Point p = new Point(0, 0);
            g.DrawString("这是在窗体上里写字！", new Font("宋体", 20), ft, p);
        }
    }
}

Answer 3

protected override void OnPaint(PaintEventArgs e)//绿色请注意override的是窗体的OnPaint！

Answer 4

仅供参考：onPaint的参数e中有graphic，e.Graphics 请用它来绘制。
不要忘记调用base.onPaint(e);附：修改你的代码protected override void OnPaint(PaintEventArgs e)
        {
            PointF pf = new PointF(200, 200);
            Font f = new Font("Arial", 12);
            e.Graphics.DrawString("Hello!", f, Brushes.Green, pf);
            base.OnPaint(e);
        }

Answer 5

using (var _Graphics = this.pictureBox1.CreateGraphics()) {
 var _BSolid  = new SolidBrush(Color.Black);   
_Graphics.DrawString("欲输出内容", this.Font, _BSolid ,ClientSize.Width - 60, 20);
_BSolid.Dispose();
 }
