通过SimpleAction显示一个listview

private void simpleAction1_Execute(object sender, SimpleActionExecuteEventArgs e) {

           IObjectSpace os = Application.CreateObjectSpace();

             string listViewId = Application.FindListViewId(typeof(Contact));

           CollectionSourceBase cs = Application.CreateCollectionSource(os, typeof(Contact), listViewId);

           e.ShowViewParameters.CreatedView = Application.CreateListView( listViewId,cs, true);

           //Specify various display settings.
           e.ShowViewParameters.Context = TemplateContext.View;
           //Determines where to show the ListView;
           e.ShowViewParameters.TargetWindow = TargetWindow.NewModalWindow;

       }
