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; 


  } 


 }
}
