這篇文章主要介紹了WPF ProgressBar實(shí)現(xiàn)實(shí)時(shí)進(jìn)度效果，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了WPF ProgressBar實(shí)現(xiàn)實(shí)時(shí)進(jìn)度的具體代碼，供大家參考，具體內(nèi)容如下

簡(jiǎn)單測(cè)試，頁(yè)面如圖：

利用上班的一點(diǎn)點(diǎn)空閑時(shí)間，做了個(gè)wpf progressbar的例子，覺得有潛力可挖，故放上來(lái)供大家參考，有寫的更好的請(qǐng)留言哦，方便交流學(xué)習(xí)，謝謝

這個(gè)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(jìn)度條控制</Button>
  <TextBlock Name="txtJD" VerticalAlignment="Top" HorizontalAlignment="Center" Margin="50">當(dāng)前進(jìn)度：</TextBlock>
  <ProgressBar Height="20" HorizontalAlignment="Center" Margin="8,167,0,0" 
Name="pb_import" VerticalAlignment="Top" Width="500" />
 </Grid>
</Page>

后臺(tái)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(huán)次數(shù)
   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(shù)據(jù)或費(fèi)時(shí)的操作，我這里讓它掛起300毫秒
    Thread.Sleep(300);
    txtJD.Text = "當(dāng)前的進(jìn)度是:" + (value + 1) + "(實(shí)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; 


  } 


 }
}
