问题 Is it possible to cast a ListBox.SelectedObjectCollection to a ListBox.ObjectCollection in C#? If so, how would I go about it? 回答1: I have a function that accepts List<string> . I can pass both SelectedItems and Items by casting them. Try this: SelectedItems.Cast<string>().ToList() Items.Cast<string>().ToList() <string> could be replaced with some other object type. 回答2: This is not possible. Instead, you should use an IList . Both of these types implement IList , so you can pass either one

How to get item list from wxpython ListBox

All that I can think to do is to set the selection to all of the items and then get the selected items, though seems like an ugly roundabout way of doing something that should be simple. Update: As pointed out by jeremy the way to do this is with GetStrings() e.g. listBoxList = yourListBox.GetStrings() 回答1: wx.ListBox
