关于C#的 error CS0123: No overload for 'PaintHandler1' matches delegate 'System.Windows.Forms.PaintEven

 public static void Main()
        {
            Form1 form = new Form1();
            form.Text = "Two Paint Handlers";
            form.BackColor = Color.White;
            form.Paint += new PaintEventHandler(PaintHandler1);
            form.Paint += new PaintEventHandler(PaintHandler2);


            Application.Run(form);
        }


        static void PaintHandler1(Object objSender, PaintEventHandler pea)
        {
            Form1 form = (Form1)objSender;
            Graphics grfx = pea.Graphics;
            grfx.DrawString("First Paint Event Handler", form.Font, Brushes.Black, 0, 0);

        }

写代码的时候敲出了如下的错误，error CS0123: No overload for 'PaintHandler1' matches delegate 'System.Windows.Forms.PaintEven

发现具体原因是因为滥用代码补全，把PaintEventArgs 敲成了 PaintEventHandler

正确写法：

 static void PaintHandler1(Object objSender, PaintEventArgs pea)
