效果图
xaml代码
<Window x:Class="ProgressBar.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:ProgressBar"
mc:Ignorable="d"
Title="MainWindow" Height="250" Width="400">
<Grid>
<ProgressBar Name="progressBar" Minimum="1" Maximum="1000" Height="50"/>
<Button Content="Done" VerticalAlignment="Bottom" HorizontalAlignment="Center" FontSize="20" Margin="10" Click="Button_Click"/>
</Grid>
</Window>
后台代码
using System;
using System.Windows;
using System.Windows.Controls.Primitives;
using System.Windows.Threading;
namespace ProgressBar
{
/// <summary>
/// MainWindow.xaml 的交互逻辑
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private delegate void UpdateProgressBarDelegate(DependencyProperty dp, object value);
private void Button_Click(object sender, RoutedEventArgs e)
{
UpdateProgressBarDelegate updateProgressBaDelegate = new UpdateProgressBarDelegate(progressBar.SetValue);
for (int i = (int)progressBar.Minimum; i <= (int)progressBar.Maximum; i++)
{
Dispatcher.Invoke(updateProgressBaDelegate, DispatcherPriority.Background, new object[] { RangeBase.ValueProperty, Convert.ToDouble(i) });
}
}
}
}
