I have a List which holds a bunch of objects, the contents of the list is then added to a listbox control. My question is, how can I remove the current item in the list which will in turn remove the current item in the listbox?

推荐答案

您只需在selectedindex_changed事件处理程序中获取选定的索引，然后删除该索引处的对象并重新填充列表框即可.

you can just get the selected index in the selectedindex_changed event handler, remove the object at that index and repopulate the listbox

int index = listbox.SelectedIndex();
listThatHoldsObjects.RemoveAt(index); 
listbox.ItemsSource = listThatHoldsObjects
