Answer 1

Let's say your listbox is called ListBox1 and textbox is TextBox1. Then the code you need is

TextBox1.Text = ListBox1.Items.Count.ToString();

Of course knowing your platform (WinForms, WebForms, Html etc.) would help a lot for a more accurate answer.

I would like to present an answer for the people who uses WPF.

<ListBox  ItemsSource="{Binding Path=Parts}">                   
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal" >
                <Label Content="{Binding CurrentPart, Mode=OneWay}" />
                <Label Content="{Binding Path=Parts.Count}"                           
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>
