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>
后臺代碼:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using System.Threading; namespace WpfBrowserAppDrill { /// <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; } } }
