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;
}
}
}
