时间：2022-12-21 20:20:30
1.说明

之前做过一个小项目，点击按钮，按钮进入倒计时无效状态，计时完成后，恢复原样，现在就实现该效果---带倒计时的按钮

2.效果

1）正常状态WPF自定义控件之带倒计时的按钮--Button               2）MouseOver(只有背景色变化)WPF自定义控件之带倒计时的按钮--Button         3）点击进入无效状态WPF自定义控件之带倒计时的按钮--Button

4）在无效状态下计时WPF自定义控件之带倒计时的按钮--Button              5）恢复正常状态WPF自定义控件之带倒计时的按钮--Button

3.XAML代码 
 <!--冷却计时按钮样式-->

       <!--通过修改颜色值参数，以更改按钮颜色样式，更多修改，还请自行DIY-->
       <SolidColorBrush x:Key="ButtonForeground" Color="#FFF9FBFD"/>
