C# WPF获取代码中列表框内的复选框

我有这个列表框，我想搜索用户选择的项目（IsChecked=true）

我还以这种方式绑定数据：

//staff is my entity object containing Id, FirstName, LastName, CellphoneNumber
lstStaffs.ItemsSource = args.Result; // comes from webservice call and is Staff[]
lstStaffs.UpdateLayout();

但是我在lststaff.Items中得到了Staff对象！！，那么，我如何迭代选定的（IsChecked=true）项（staff）

Tnx

来自MSDN页面：

// Getting the currently selected ListBoxItem 
// Note that the ListBox must have 
// IsSynchronizedWithCurrentItem set to True for this to work
ListBoxItem myListBoxItem = (ListBoxItem)(myListBox.ItemContainerGenerator.
    ContainerFromItem(myListBox.Items.CurrentItem));

// Getting the ContentPresenter of myListBoxItem
ContentPresenter myContentPresenter = FindVisualChild<ContentPresenter>(myListBoxItem);

// Finding textBlock from the DataTemplate that is set on that ContentPresenter
DataTemplate myDataTemplate = myContentPresenter.ContentTemplate;
TextBlock myTextBlock = (TextBlock)myDataTemplate.FindName("textBlock", 
    myContentPresenter);

// Do something to the DataTemplate-generated TextBlock
MessageBox.Show("The text of the TextBlock of the selected list item: "
    + myTextBlock.Text);

您必须将

SelectionMode

设置为

Multiple

或

Extended

，才能使其工作

如果要获取选定的项目，则需要使用SelectedItems属性您可能还需要禁用虚拟化，否则，

ContainerFromItem（）

将在不可见的项目上返回

null

。

//staff is my entity object containing Id, FirstName, LastName, CellphoneNumber
lstStaffs.ItemsSource = args.Result; // comes from webservice call and is Staff[]
lstStaffs.UpdateLayout();

// Getting the currently selected ListBoxItem 
// Note that the ListBox must have 
// IsSynchronizedWithCurrentItem set to True for this to work
ListBoxItem myListBoxItem = (ListBoxItem)(myListBox.ItemContainerGenerator.
    ContainerFromItem(myListBox.Items.CurrentItem));

// Getting the ContentPresenter of myListBoxItem
ContentPresenter myContentPresenter = FindVisualChild<ContentPresenter>(myListBoxItem);

// Finding textBlock from the DataTemplate that is set on that ContentPresenter
DataTemplate myDataTemplate = myContentPresenter.ContentTemplate;
TextBlock myTextBlock = (TextBlock)myDataTemplate.FindName("textBlock", 
    myContentPresenter);

// Do something to the DataTemplate-generated TextBlock
MessageBox.Show("The text of the TextBlock of the selected list item: "
    + myTextBlock.Text);

var selectedItems = lstStaffs.SelectedItems;
