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; } } }
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
