1.ProgressBar 控件介绍
进度条 ：显示某个操作的进度过程 。
Maximum Minimum Orientation Value IsIndeterminate
2.具体案例
<Grid>
<!--Orientation 进度条的方向 默认水平 IsIndeterminate 指示进度是显示实际值 true 连续进度反馈-->
<ProgressBar HorizontalAlignment="Left" Orientation="Vertical" IsIndeterminate="True" Value="40" Minimum="0" Maximum="80" Height="299" Margin="49,89,0,0" VerticalAlignment="Top" Width="98"/>
<ProgressBar Name="pbar2" HorizontalAlignment="Left" Minimum="0" Maximum="100" Orientation="Horizontal" SmallChange="2" Height="29" Margin="287,201,0,0" VerticalAlignment="Top" Width="412" ValueChanged="Pbar2_ValueChanged" >
</ProgressBar>
<Button Content="加载" HorizontalAlignment="Left" Margin="287,328,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click"/>
<Label Name="lblVal" HorizontalAlignment="Left" Margin="287,252,0,0" VerticalAlignment="Top" Height="28" Width="51"/>
</Grid>
private void Button_Click(object sender, RoutedEventArgs e)
{
//pbar2.Value = 0;
//for (int i = 0; i < pbar2.Maximum; i++)
//{
// pbar2.Value = i;
// lblVal.Content = pbar2.Value + "%";
// Thread.Sleep(100);
//}
int max = 50;
Task.Run(() =>
{
for (int i = 0; i <= max; i++)
{
pbar2.Dispatcher.Invoke(() =>
{
pbar2.Value = i;
//lblVal.Content = pbar2.Value + "%";
});
Thread.Sleep(100);
}
});
}
private void Pbar2_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
