进度显示界面使用UserControl把ProgressBar和进度值以及要显示的内容全部组装在UserControl界面中方便其他界面直接进行使用。

/UserControl进度显示界面UserControl 后台逻辑实现主要定义了进度值、显示的文本、以及UserControl的大小。

}在MainWindow界面中调用[进度显示界面]示例如下

/Window后台模拟进度变化使用Task任务更新进度值代码示例如下

using System.Windows.Shapes;namespace DefProcessBarDemo

}运行时点击【点击】按钮即可看到进度持续不断地更新界面如下图所示
