C#winform实现像触摸屏按钮那样的开关

触摸屏的按钮开发起来非常方便，只要设置好样式和文本，以及绑定的变量，一个开关就做好了。

而用winform要实现同样的功能，要编写许多代码。

花木兰控件库的ToggleButton可以这样做切换，但是有几点不方便的地方。于是修改了以下几点：

1. 文本修改成可以换行：
   
   文本居中且可以自动换行，而且通过修改Padding可以设置每一行显示多少个字，比如我要改成每行最多三个字：
   
2. 圆角修改成可以设置
   
3. 点击时切换文本
   
   
   
   最终效果就是点击切换状态、背景和文本。
   查看按钮的状态。

private void toggleButton1_Click(object sender, EventArgs e)
{
   
    HML.ToggleButton btn = (HML.ToggleButton)sender;
    MessageBox.Show(btn.Checked.ToString());
}

控件库源码：添加链接描述
打开解决方案把 HML 项目里面的 ToggleButton 的代码替换成下面的代码，把HML项目重新生成，获得 HML.ComplexityPropertys.dll 和 HML.dll 文件，引入自己的项目即可。
