进度条是比较简单，前台一个进度条，后台给value赋值0到100就可以显示进度了。

完整代码：

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;namespace 进度条
{/// <summary>/// Interaction logic for MainWindow.xaml/// </summary>public partial class MainWindow : Window{public MainWindow(){InitializeComponent();}private async void Button_Click(object sender, RoutedEventArgs e){Button button = (Button)sender;button.IsEnabled = false;await WaitAsync();button.IsEnabled = true;}public async Task WaitAsync(){for(int i = 0; i <= 100; i++){await Task.Delay(50);ProgressBar1.Value = i;使用调度器在UI线程上更新进度条,不过在这里不使用Dispatcher.Invoke也可以//System.Windows.Application.Current.Dispatcher.Invoke(() =>//{//    progressBar.Value = i; // 更新进度条的值//});}}}
}
