WPF ProgressBar实现实时进度效果
作者：秋秋_瑶瑶
这篇文章主要介绍了WPF ProgressBar实现实时进度效果，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
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;
}
}
}
