You can bind the IsCheckedproperty directly to IsSelectedof the ListViewItem. Use RelativeSourceto bind to the element.
您可以将该IsChecked属性直接绑定到IsSelectedListViewItem。使用RelativeSource绑定到元素。
IsChecked="{Binding RelativeSource={RelativeSource AncestorType=ListViewItem},Path=IsSelected}"
Now if you use SelectionMode=Multiplefor the ListView, you can pull the checked items directly using SelectedItems.
现在，如果您SelectionMode=Multiple用于 ListView，则可以直接使用SelectedItems.
var chapters = new List<Chapter>();
foreach (var item in listViewChapter.SelectedItems)
users.Add((Chapter)item);

You should consider using the MVVM patternfor your WPF application, and if you're going to use MVVM then you'll want an MVVM framework.
您应该考虑为您的 WPF 应用程序使用MVVM 模式，如果您打算使用 MVVM，那么您将需要一个 MVVM 框架。
Then, it would be a case of creating a type that represents your databound object (e.g Book), then having a collection of this type on your view model (e.g. ObservableCollection<Book> Books).
然后，这将是创建一个代表您的数据绑定对象（例如Book）的类型，然后在您的视图模型（例如ObservableCollection<Book> Books）上拥有这种类型的集合的情况。
You would then bind a Selectedboolean property for example on your Booktype to the CheckBox's IsCheckedproperty in your ListBox ItemTemplate.
然后，您可以将类型Selected上的布尔属性绑定Book到IsCheckedListBox ItemTemplate 中的 CheckBox属性。
<CheckBox IsChecked="{Binding Selected}" />
You may not want to polute your domain object (Book) with properties purely used for the UI (Selected), so you could create a BookViewModeltype which augments the Booktype and reshapes the object purely for the purposes of the view.
您可能不想Book使用纯粹用于 UI ( Selected) 的属性来污染域对象 ( ) ，因此您可以创建一个BookViewModel类型来扩充Book类型并纯粹为了视图的目的而重塑对象。
