c# - 从 SelectionChangedEventArgs e Windows Phone 8 获取对象

Question

我正在使用 Telerik Slide View 控件，它支持SelectionChanged事件

private void radSlideView_SelectionChanged(object sender, SelectionChangedEventArgs e)
{        
    var addedItems = e.AddedItems;
}

e包含MainViewModel包含该属性的对象FileName。我如何“提取”FileName财产e？addedItems是一种System.Collection.IList类型

Answer 1

你需要投：

if(e.AddedItems.Length > 0)       // make sure there is at least one item..
{
   MainViewModel firstItem = e.AddedItems[0] as MainViewModel;    // cast..
   if(firstItem != null)                                          // if not null..
   {
       string fileName = firstItem.FileName;                      // get the file name
   }
}
