检索列表框多个选定项 [英] Retrieve ListBox Multiple Selected Items

问题描述

我有一个ListBox，其中有一个绑定到itemsSource的项目列表.列表框选择模式设置为扩展，以便用户可以选择多个项目.由于列表框仅具有SelectedItem属性，因此我可以将其绑定到ViewModel中的属性以仅获取一个 选定的项目.

I have a ListBox that has a list of items binded to a itemsSource. Listbox selection mode is set to extended so that user can selected multiple items. As Listbox has only SelectedItem property which I can a bind to a property in ViewModel to get only one selected item.

由于此控件有多个选择，因此我需要多个选择的项目.因此，如何利用MVVM方法从列表框中获取选定的项目.

As this control has multiple selections, I want multiple selected items. So, how can I can make use of MVVM approach to get the selected items from Listbox.

我不想使用交互触发器方法.还有什么其他方法可以从ListBox中获取选定的项目.

I don't want to use interaction triggers approach. Is there any other way I can get the selected items from ListBox.
