如何在wpf中更新进度条和文本块的值

我是wpf和c#的新手，也在这里问。我在网上搜索了几个小时，我还没有找到解决我问题的方法。我有一个进度条，每当循环增加时更新它的值，一个文本块更新它的文本(例如:阅读行5/3000)。目前，我没有绑定路径，所以我在xaml中创建了一个虚拟绑定。我不知道该怎么做。

这是我的XAML:

<xctk:BusyIndicator x:Name="_busyIndicator" Grid.Row="4">
                <xctk:BusyIndicator.BusyContentTemplate>
                    <DataTemplate>
                        <StackPanel Margin="4">
                            <TextBlock Text="Parsing OTM File" FontWeight="Bold" HorizontalAlignment="Center" />
                            <StackPanel Margin="4">
                                <TextBlock Text="{Binding NumberOfLinesOfStringInTextFile}" />
                                <ProgressBar Grid.Row="4" Name="prgParse" Height="15" Value="{Binding CurrentLineNumberAddedToListView}" />
                            </StackPanel>
                        </StackPanel>
                    </DataTemplate>
                </xctk:BusyIndicator.BusyContentTemplate>
                <xctk:BusyIndicator.OverlayStyle>
                    <Style TargetType="Rectangle">
                        <Setter Property="Fill" Value="#ffffeeee"/>
                    </Style>
                </xctk:BusyIndicator.OverlayStyle>
                <xctk:BusyIndicator.ProgressBarStyle>
                    <Style TargetType="ProgressBar">
                        <Setter Property="Visibility" Value="Collapsed"/>
                    </Style>
                </xctk:BusyIndicator.ProgressBarStyle>
                <ListBox x:Name="_listBox" />
            </xctk:BusyIndicator>

我有一个按钮，触发读取文本文件内的行循环(在这种情况下，它有3000+行)，并将字符串行放置到listview。我想在我的xaml中更新文本块，声明"阅读行300/3000"和进度条，指示它的百分比，更新其值为10%或10%，而它正在将数据传输到列表视图。

下面是我的代码:

 public partial class MainWindow : Window, INotifyPropertyChanged
    {
        public MainWindow()
        {
            InitializeComponent();
            DataContext = this;
        }
        private void cmdBrowse_Click(object sender, RoutedEventArgs e)
        {
            var OpenOTM = new Microsoft.Win32.OpenFileDialog();
            OpenOTM.DefaultExt = ".otm";
            OpenOTM.Filter = "OTM Files (*.otm)|*.otm|TEXT Files (*.txt)|*.txt"; 
            if (OpenOTM.ShowDialog().GetValueOrDefault(false))
            {
                txtFilePath.Text = OpenOTM.FileName;
            }
        }
        private void cmdOk_Click(object sender, RoutedEventArgs e)
        {
            WithAdjustments wa = new WithAdjustments();
            BackgroundWorker worker = new BackgroundWorker();
            string[] lines = System.IO.File.ReadAllLines(txtFilePath.Text);
            worker.DoWork += (o, ea) =>
            {
                List<String> listOfString = new List<string>();
                foreach (string lin in lines)
                {
                    listOfString.Add(lin);
                    Thread.Sleep(2);
                }
                Dispatcher.Invoke((Action)(() => _listBox.ItemsSource = listOfString));
            };
            worker.RunWorkerCompleted += (o, ea) =>
            {
                _busyIndicator.IsBusy = false;
            };
            _busyIndicator.IsBusy = true;
            worker.RunWorkerAsync();
        }
    }

提前感谢!我希望有人能帮助我:)

worker.WorkerSupportsCancellation = true;
worker.WorkerReportsProgress = true;
worker.ProgressChanged += (o, e) =>
{
     //Here in e.ProgressPercentage you will get the current line number read you can deduct the textblock text and progressbar value to be set on CurrentLineNumberAddedToListView and NumberOfLinesOfStringInTextFile
}
worker.DoWork += (o, ea) =>
        {
            List<String> listOfString = new List<string>();
            BackgroundWorker worker = o as BackgroundWorker;
            int numberofLine = 0;
            foreach (string lin in lines)
            {
                listOfString.Add(lin);
                o.ReportProgress(++numberofLine);
                Thread.Sleep(2);
            }

            Dispatcher.Invoke((Action)(() => _listBox.ItemsSource = listOfString));
        };
