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;        }
