提问by Hendra Anggrian

I know that:

我知道:

String test = "test";
ListBox.Items.Add(test);

or

或者

String test = "test";
int index = 1;
ListBox.Items.Insert(index, String);

adds the String in a ListBox, but I want to insert ListBoxItem, how to? previously I learn that

在 ListBox 中添加 String,但我想插入 ListBoxItem,如何?以前我了解到

var contentToString = (String)ListBoxItem.Content;

simply converts ListBoxItem to String, but I couldn't do the opposite to convert String to ListBoxItem

只是将 ListBoxItem 转换为 String,但我不能做相反的操作将 String 转换为 ListBoxItem

采纳答案by Danilo Vulovi?

Try this:

尝试这个:

ListBoxItem itm = new ListBoxItem();
itm.Content = "some text";

listbox.Items.Add(itm);

listbox is name for ListBox.

listbox 是 ListBox 的名称。

You can do like that

你可以这样做

ListBox1.Items.Insert(0,new ListItem("ITEM 1", "Value"))

回答by Dtex

Your object will always be in a ListBoxItem, the ListBox will generate one for you if you don't add it explicitly. To get the ListBoxItem you use:

您的对象将始终位于 ListBoxItem 中,如果您不明确添加,ListBox 将为您生成一个。要获取您使用的 ListBoxItem:

var listboxitem = (ListBoxItem)listbox.ItemContainerGenerator.ContainerFromItem(myItem);
