推荐答案
Button {index ++}}）;
Console.WriteLine（string.Format（你点击了{0}。按钮。，（发件人为Button）.Tag））;
}
private void DeleteButton_Click（object sender，RoutedEventArgs e）
{
}
private void RefreshButton_Click（object发件人，RoutedEventArgs e）
{
}
}
}
"Button {index++}"}); Console.WriteLine(string.Format("You clicked on the {0}. button.", (sender as Button).Tag)); } private void DeleteButton_Click(object sender, RoutedEventArgs e) { } private void RefreshButton_Click(object sender, RoutedEventArgs e) { } } }
如果你正确的话构建您的viewmodel并将其绑定到控件，您所要做的就是修改viewmodel，当控件检测到绑定列表中的项目发生更改时，控件将自动更新。我希望你的导师在分配这个作业之前和你一起讨论这个问题。
如果不是功课，你应该考虑一个新的职业。
If you properly construct your viewmodel and bind it to the control, all you have to do is modify the viewmodel, and the control will automagically update itself when it detects a change to the items in the bound list. I'm hoping your instructor went over this with you before assigning this homework.
If it is not indeed homework, you should consider a new career.
我没有看到你的.cs代码中使用的ObservableCollection。
见这里的例子：如何：创建并绑定到ObservableCollection [ ^ ]
在这里： Mitesh Sureja的博客：将ObservableCollection绑定到WPF中的ListBox [< a href =http://miteshsureja.blogspot.nl/2011/07/binding-observablecollection-to-listbox.html\"target =_ blanktitle =New Window> ^ ]
I don't seeObservableCollectionbeing used in your .cs code.
See example here: How to: Create and Bind to an ObservableCollection[^]
And here: Mitesh Sureja's Blog: Binding ObservableCollection to ListBox in WPF[^]
