WPF ProgressBar实现实时进度效果

本文实例为大家分享了WPF ProgressBar实现实时进度的具体代码，供大家参考，具体内容如下

简单测试，页面如图：

利用上班的一点点空闲时间，做了个wpf progressbar的例子，觉得有潜力可挖，故放上来供大家参考，有写的更好的请留言哦，方便交流学习，谢谢

这个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">进度条控制</Button>
 <TextBlock Name="txtJD" VerticalAlignment="Top" HorizontalAlignment="Center" Margin="50">当前进度：</TextBlock>
 <ProgressBar Height="20" HorizontalAlignment="Center" Margin="8,167,0,0"
Name="pb_import" VerticalAlignment="Top" Width="500" />
</Grid>
</Page>

后台代码：

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 的交互逻辑
/// </summary>
public partial class ProgressBarPage : Page
{

public ProgressBarPage()
 {
  InitializeComponent();
 }

private void beginImport()
 {
  double value = 0;
  double total = 100d;//得到循环次数
  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);
   //这里是加数据或费时的操作，我这里让它挂起300毫秒
   Thread.Sleep(300);
   txtJD.Text = "当前的进度是:" + (value + 1) + "(实际值)" + 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;

}

}
}
