C#非矩形窗体实现方法
本文实例讲述了C#非矩形窗体实现方法。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;
usingSystem.Drawing.Drawing2D;
namespaceWindowsApplication1
{
publicpartialclassForm3:Form
{
PointdownPoint=Point.Empty;
publicForm3()
{
InitializeComponent();
}
voidSet()
{
Rectanglerect=this.ClientRectangle;
using(GraphicsPathpath=newGraphicsPath())
{
path.AddEllipse(rect);
this.Region=newRegion(path);
}
}
privatevoidForm3_Load(objectsender,EventArgse)
{
Set();
}
privatevoidForm3_MouseDown(objectsender,MouseEventArgse)
{
if(e.Button!=MouseButtons.Left)return;
downPoint=newPoint(e.X,e.Y);
}
privatevoidForm3_MouseMove(objectsender,MouseEventArgse)
{
if(downPoint==Point.Empty)return;
Pointlocation=newPoint(this.Left+e.X-downPoint.X,this.Top+e.Y-downPoint.Y);
this.Location=location;
}
privatevoidForm3_MouseUp(objectsender,MouseEventArgse)
{
if(e.Button!=MouseButtons.Left)return;
downPoint=Point.Empty;
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
