C#处理Paint事件的方法

本文实例讲述了c#处理paint事件的方法。分享给大家供大家参考。具体方法如下：

using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.text;
using system.windows.forms;
namespace windowsapplication2
{
  public partial class form5 : form
  {
    bool drawelipse = false;
    public form5()
    {
      initializecomponent();
      this.setstyle(controlstyles.resizeredraw, true);
    }
    private void form5_load(object sender, eventargs e)
    {
    }
    private void button1_click(object sender, eventargs e)
    {
      this.drawelipse = !this.drawelipse;
      this.invalidate(true);
    }
    private void form5_paint(object sender, painteventargs e)
    {
      if (!this.drawelipse) return;
      graphics g = e.graphics;
      g.fillellipse(brushes.darkblue, this.clientrectangle);
    }
  }
}

希望本文所述对大家的c#程序设计有所帮助。
