本文實例為大家分享了WPF ProgressBar實現實時進度的具體代碼，供大家參考，具體內容如下
簡單測試，頁面如圖：
利用上班的一點點空閑時間，做了個wpf progressbar的例子，覺得有潛力可挖，故放上來供大家參考，有寫的更好的請留言哦，方便交流學習，謝謝
這個xaml:
<Page x:Class="WpfBrowserAppDrill.ProgressBarPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" Title="ProgressBarPage" Loaded="Page_Loaded"> <Grid> <Button Margin="10" Click="Button_Click" VerticalAlignment="Top" Height="23" Width="100">進度條控制</Button> <TextBlock Name="txtJD" VerticalAlignment="Top" HorizontalAlignment="Center" Margin="50">當前進度：</TextBlock> <ProgressBar Height="20" HorizontalAlignment="Center" Margin="8,167,0,0" Name="pb_import" VerticalAlignment="Top" Width="500" /> </Grid> </Page>

/// <summary>
/// ProgressBarPage.xaml 的交互邏輯
/// </summary>
public partial class ProgressBarPage : Page
{
public ProgressBarPage()
{
InitializeComponent();
}
private void beginImport()
{
double value = 0;
double total = 100d;//得到循環次數
while (value < total)
{
double jd = Math.Round(((value + 1) * (pb_import.Maximum / total)), 4);
pb_import.Dispatcher.Invoke(new Action<System.Windows.DependencyProperty, object>(pb_import.SetValue),
System.Windows.Threading.DispatcherPriority.Background,
ProgressBar.ValueProperty,
jd);
//這里是加數據或費時的操作，我這里讓它掛起300毫秒
Thread.Sleep(300);
txtJD.Text = "當前的進度是:" + (value + 1) + "(實際值)" + jd + "(百分比)";
value++;
}
}
private void Button_Click(object sender, RoutedEventArgs e)
{
beginImport();
////new Thread(new ThreadStart(beginImport)).Start();
}
private void Page_Loaded(object sender, RoutedEventArgs e)
{
pb_import.Maximum = 100;
pb_import.Value = 0;
}
}
}
