C#绘制椭圆的方法

本文实例讲述了c#绘制椭圆的方法。分享给大家供大家参考。具体实现方法如下：

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 form4 : form
  {
    public form4()
    {
      initializecomponent();
    }
    bool drawelipse = false;
    private void button1_click(object sender, eventargs e)
    {
      this.drawelipse = !this.drawelipse;
      using (graphics g = this.creategraphics())
      {
        if (this.drawelipse)
        {
          g.fillellipse(brushes.darkblue, this.clientrectangle);
        }
        else
        {
          g.fillellipse(systembrushes.control, this.clientrectangle);
        }
      }
    }
    private void form4_load(object sender, eventargs e)
    {
    }
  }
}

希望本文所述对大家的c#程序设计有所帮助。
