How to get selected ListView Item?

WPF Listview Access to SelectedItem and subitems
I have a listview in my xaml and I want to get the selected item in the code-behind. In fact I would like to get the content of the item (which is an object). I've tried to do MyListView.SelectedItems[0] but it doesn't work, I have "accessor get or set expected".
我的 xaml 中有一个列表视图，我想在代码隐藏中获取所选项目。事实上，我想获取项目的内容（这是一个对象）。我试过 MyListView.SelectedItems[0] 但它不起作用，我有“访问器获取或设置预期”。

How are you using it? It should be MyListView.SelectedItems[0].
你如何使用它？应该是MyListView.SelectedItems[0]。
MyObject foo = (MyObject)MyListView.SelectedItems[0];
You should probably add some checks if SelectedItemscontains actual items and the SelectedItemobject is indeed a MyObject, but you get the idea.
如果SelectedItems包含实际项目并且SelectedItem对象确实是 a MyObject，您可能应该添加一些检查，但您明白了。
Also if you select a single item there is SelectedItem, I think.
此外，如果您选择单个项目SelectedItem，我认为。
回答by ie.
I guess you should use SelectedItemnot SelectedItems:
我想你应该使用SelectedItem而不是SelectedItems：
This property is meant to be used when SelectionMode does not equal Single. If the selection mode is Single the correct property to use is SelectedItem.
此属性旨在在 SelectionMode 不等于 Single 时使用。如果选择模式为 Single，则要使用的正确属性是 SelectedItem。
