C#中WPF中简单进度条的实现

C#中WPF简单进度条的实现

前端代码

  <ProgressBar Name="pbar" Margin="350,6,120,6" VerticalAlignment="Center" Height="36" Minimum="0" Maximum="1" >
                        
                        <ProgressBar.Foreground>
                            <LinearGradientBrush >
                                <GradientStop Color="#1296DB" Offset="0"/>
                            </LinearGradientBrush>
                        </ProgressBar.Foreground>
                    </ProgressBar>
                    <TextBlock Name="txtPercent" Margin="620,12,270,10" RenderTransformOrigin="0.812,0.5" VerticalAlignment="Center"/>

后台代码：

 for(int i=1;i<=1000;i++)\
{
    double l = (double)i/ 1000;
 pbar.Dispatcher.Invoke(new Action<System.Windows.DependencyProperty, object>(pbar.SetValue), System.Windows.Threading.DispatcherPriority.Background, ProgressBar.ValueProperty, l);//更新进度条的进度；
this.txtPercent.Dispatcher.Invoke(new Action(() => { txtPercent.Text = Convert.ToInt32((l * 100)).ToString() + "%"; })); //使用一个textBlock控件，在进度条上显示百分比；
}




// Dispatcher.Invoke(new Action<System.Windows.DependencyProperty, object>(Pro.SetValue), System.Windows.Threading.DispatcherPriority.Background, new object[] { ProgressBar.ValueProperty, Convert.ToDouble(percent+ 1) });
