试图从另一个线程访问SelectedIndex

我需要从另一个线程访问TabControl的SelectedIndex属性，我尝试了这样的Dispatcher:

public ListView CurrentTab
{
    get
    {
        ListView listView = null;
        Action action = () =>
        {
            int currentTab = MainWindow.AppWindow.TabControl.SelectedIndex;
            //Check wich tab is opened
            switch (currentTab)
            {
                case 0: 
                    listView = MainWindow.AppWindow.PlayingControl.Playing;
                    break;
                case 1:
                    listView = MainWindow.AppWindow.AllMatchesControl.AllMatches;
                    break;
                case 2: 
                   listView = MainWindow.AppWindow.CustomMatchesControl.CustomMatches;
                    break;
            }
        };
        Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(action));
            return listView;
        }
 }

但是我得到

系统。InvalidOperationException

调用线程无法访问对象，因为该对象由另一个线程属性拥有。

我试图通过SelectedIndex返回一个列表，我做错了什么?

int currentTab = 0;
MainWindow.AppWindow.TabControl.Dispatcher.Invoke(() => {
  currentTab = MainWindow.AppWindow.TabControl.SelectedIndex;
});

public ListView CurrentTab
{
    get
    {
         return (ListView)this.Dispatcher.Invoke(
          new Func<ListView>(() => 
          { 
              ListView listView = null;
              int currentTab = tabControl.SelectedIndex;
                switch (currentTab)
                {
                    case 0:
                        listView = new ListView();
                        listView = list_1;
                        break;
                    case 1:
                        listView = list_2;
                        break;
                    case 2:
                        listView = list_3;
                        break;
                }
                return listView;
          }));
    }
}
