(四十)c#Winform自定义控件-开关

准备工作

GDI+需要有一点了解,不知道的可以百度瞅瞅

开始

添加一个用户控件,命名UCSwitch

添加一个枚举用以控制样式

public enum SwitchType
    {
        /// <summary>
        /// 椭圆
        /// </summary>
        Ellipse,
        /// <summary>
        /// 四边形
        /// </summary>
        Quadrilateral,
        /// <summary>
        /// 横线
        /// </summary>
        Line
    }

添加属性
