用VS建两个项目(CustomControlSample, TestControl), 项目类型分别是类库(不是内裤!!!), Windows应用程序.
1
using System.Windows.Forms;
2using System.Drawing;
3
4namespace CustomControlSample
5
{
6
public class FirstControl : Control
7
{
8 private int simpleField;
9
10 public int SimpleProperty
11 {
12 get { return simpleField; }
13 set { simpleField = value; }
14
}
15
16 protected override void OnPaint(PaintEventArgs e)
17 {
18 base.OnPaint(e);
19 e.Graphics.DrawRectangle(Pens.Red, new Rectangle(Point.Empty, new Size(Width - 1, Height - 1)));
20 }
21 }
22
}

}只有一个属性的控件!!!
拖到windows 窗体上:
在属性浏览器中可以看到该控件的唯一属性:
一个最最简单的Dot net winform控件做好了.
The end.
