首页 / 网页编程 / ASP.NET / 仿vs实现WPF好看的进度条

为了界面友好,一般的操作时间较长时,都需要增加进度条提示。由于WPF自带的进度条其实不怎么好看,而且没啥视觉效果。后来,装VS2012时,发现安装过程中进度条效果不错,于是上网查了资料。学习了ModernUI(开源的),地址:https://github.com/firstfloorsoftware/mui。

后来,做了尝试写了个Demo,效果不错。另外,专门录制了tif文件,方便大家看到效果。废话不多说,先展示效果:

一、效果展示

A、VS2012安装界面图;

B、个人尝试Demo效果图:

二、实现说明

1、下载MUI相关代码或者dll文件;

2、工程中引入该dll,并引入其资源文件;

复制代码 代码如下:
<Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/FirstFloor.ModernUI;component/Assets/ModernUI.xaml" />
                <ResourceDictionary Source="/FirstFloor.ModernUI;component/Assets/ModernUI.Light.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>

3、在需要显示进度条的页面,加入控件(其实还是WPF控件,只是MUI扩展了其样式而已);

复制代码 代码如下:
<Label Margin="280,169,0,0" Style="{StaticResource BackGroundContentText}" x:Name="lblMainState" HorizontalAlignment="Left" VerticalAlignment="Top">正在启动:</Label>
        <ProgressBar Margin="280,200,0,0" HorizontalAlignment="Left" VerticalAlignment="Top" Width="500" Minimum="0" x:Name="ProgressControlRealValue" Maximum="1"  Value="0.1" Height="16" IsIndeterminate="False"/>
        <Label Margin="280,212,0,0" Style="{StaticResource BackGroundContentText}" x:Name="lblProcess" HorizontalAlignment="Left" VerticalAlignment="Top">正在加载地图数据...</Label>
        <ProgressBar Margin="280,250,0,0" HorizontalAlignment="Left" VerticalAlignment="Top"  Minimum="0" x:Name="ProgressControl"  Width="500" Maximum="2" Height="16" IsIndeterminate="True" />

4、后台实现,由于要根据情况更新进度文字及进度条的值。所以,这里用到了异步BackgroundWorker(具体可以网上查查相关资料);

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.ComponentModel;namespace Monitor.Class{/// <summary>/// 异步操作/// </summary>public class CWorker{/// <summary>/// 对象/// </summary>private BackgroundWorker backgroundWorker;/// <summary>/// 后台执行的操作/// </summary>public Action BackgroundWork { get; set; }/// <summary>/// 后台任务执行完毕后事件/// </summary>public event EventHandler<BackgroundWorkerEventArgs> BackgroundWorkerCompleted;private BackgroundWorkerEventArgs _eventArgs;//异常参数/// <summary>/// 构造/// </summary>public CWorker(){_eventArgs = new BackgroundWorkerEventArgs();backgroundWorker = new BackgroundWorker();backgroundWorker.WorkerReportsProgress = true;backgroundWorker.WorkerSupportsCancellation = true;backgroundWorker.DoWork += new DoWorkEventHandler(backgroundWorker1_DoWork);backgroundWorker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(backgroundWorker1_RunWorkerCompleted);}/// <summary>/// 开始工作/// </summary>public void BegionWork(){if (backgroundWorker.IsBusy)return;backgroundWorker.RunWorkerAsync();}/// <summary>/// 工作/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e){if (BackgroundWork != null){try{BackgroundWork();}catch (Exception ex){_eventArgs.BackGroundException = ex;}}}/// <summary>/// 完成/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e){if (this.BackgroundWorkerCompleted != null){this.BackgroundWorkerCompleted(null, _eventArgs);}}}/// <summary>/// 事件/// </summary>public class BackgroundWorkerEventArgs : EventArgs{/// <summary>/// 后台程序运行时抛出的异常/// </summary>public Exception BackGroundException { get; set; }}}
