ListItemCollection listBoxData = new ListItemCollection();
// Add items to the collection.
listBoxData.Add(new ListItem("apples"));
listBoxData.Add(new ListItem("bananas"));
listBoxData.Add(new ListItem("cherries"));
listBoxData.Add("grapes");
listBoxData.Add("mangos");
listBoxData.Add("oranges");
// Set the ListItemCollection as the data source for ListBox1.
ListBox1.DataSource = listBoxData;
ListBox1.DataBind();

' Create a new ListItemCollection.
Dim listBoxData As New ListItemCollection()
' Add items to the collection.
listBoxData.Add(New ListItem("apples"))
listBoxData.Add(New ListItem("bananas"))
listBoxData.Add(New ListItem("cherries"))
listBoxData.Add("grapes")
listBoxData.Add("mangos")
listBoxData.Add("oranges")
' Set the ListItemCollection as the data source for ListBox1.
ListBox1.DataSource = listBoxData
ListBox1.DataBind()
