潜移默化学会WPF--ProcessBar学习（一）

给你个demo吧

前台页面很简单

<Window x:Class="ProgressBarDemo.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="131*" />
            <RowDefinition Height="180*" />
        </Grid.RowDefinitions>
        <TextBlock Name="text" Grid.Row="0"></TextBlock>
        <ProgressBar Name="pb" Grid.Row="1"></ProgressBar>
    </Grid>
</Window>
