用处及效果

准备工作

请先了解GDI+和三角函数

开始

添加一个类UCValve，继承UserControl

添加一个阀门显示样式枚举

 1 /// <summary>
 2     /// Enum ValveStyle
 3     /// </summary>
 4     public enum ValveStyle
 5     {
 6         /// <summary>
 7         /// 横向，开关在上方
 8         /// </summary>
 9         Horizontal_Top,
10         /// <summary>
11         /// 横向，开关在下方
12         /// </summary>
13         Horizontal_Bottom,
14         /// <summary>
15         /// 纵向，开关在左侧
16         /// </summary>
17         Vertical_Left,
18         /// <summary>
19         /// 纵向，开关在右侧
20         /// </summary>
21         Vertical_Right,
22     }

添加一些属性
