事件之间如何互相调用？

Question

请帮个忙：
  用C#，我想在timeer_click（...）事件调用onpaint（....）画图事件？

Answer 1

timmer_click(){
    onPaint(this,null);
}

Answer 2

以上方法不行？
private voidobject sender, EventArgs e)
        {
          
  if (this.imageList1!= null && this.imageList1.Images.Count > 0)
            { 
               index = nCurrentindex % this.imageList1.Images.Count;
                
                nCurrentindex++;
               if (nCurrentindex > this.imageList1.Images.Count * 10)
                {
                    nCurrentindex = 0;
                }
                this.Mybutton_Paint(sender,e);
              
            }
        }
     private void Mybutton_Paint(object sender, PaintEventArgs e)
        {
            Graphics g = e.Graphics;
            Image img = imageList1.Images[index];
            g.DrawImage(img, 0, 0,32,32);
        }

Answer 3

this.Invalidate(); 此方面会触发Paint()事件.
