我有一个带有Datatemplate的ListView,它包含一个电影列表.它被数据绑定到ObservableColection,但每当我编辑Movie.Name时,即使在我的PropertyChangedEventHandler中调用"Name"并使用"Name"调用它,它也不会更新ListView.

我在我的初始化程序中为我的收藏添加了2个"电影",这些都显示正确(Klovn the Movie,Taken)

因此,当我单击编辑时,它应该更改所选电影的文本并将其名称更改为"测试"并且已更改,但更改未显示在ListView中,但如果我使用foreach输出Collection,则Name is Test.
