multiple selection in a list box

[steve_rm]

Hello

I am using the code below to add multiple items from a list box called lstNamesToAdd to another list box called lstNames.

I click multiple items and then click a button to add them. The code does not work. Can anyone tell me the best way to this

lstName.Items.Add(lstNameToAdd.SelectItems);
lstNamesToAdd.Items.Remove(lstNamesToAdd.SelectedItems);

Question 2
Does C# use a inputbox to accept input from a user?

Many thanks in advance

Steve
