2、界面

<ProgressBar Foreground="Blue" HorizontalAlignment="Center" VerticalAlignment="Center" Value="{Binding CurrentProgress, Mode=OneWay}"
Visibility="{Binding ProgressVisibility, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"/>

3、转换器

public class ProgressBarValueLocationConverter : IValueConverter
{

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return ((double)value - 25);
}

public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return 0;
}
}

public class ProgressBarValueTextFormatConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return value.ToString() + "%";
}

public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
