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：
usingSystem;
usingSystem.Collections.Generic;
usingSystem.ComponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Text;
usingSystem.Windows.Forms;
namespaceWindowsApplication2
{
publicpartialclassForm4:Form
{
publicForm4()
{
InitializeComponent();
}
booldrawElipse=false;
privatevoidbutton1_Click(objectsender,EventArgse)
{
this.drawElipse=!this.drawElipse;
using(Graphicsg=this.CreateGraphics())
{
if(this.drawElipse)
{
g.FillEllipse(Brushes.DarkBlue,this.ClientRectangle);
}
else
{
g.FillEllipse(SystemBrushes.Control,this.ClientRectangle);
}
}
}
privatevoidForm4_Load(objectsender,EventArgse)
{
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
