    MenuItem menuItemOpen = new MenuItem();
    menuItemOpen.Click += new RoutedEventHandler(menuItemOpen_Click);
    contextMenu.Items.Add(menuItemOpen);
    listBox1.ContextMenu = contextMenu;
}
void menuItemOpen_Click(object sender, RoutedEventArgs e)
{
    //How do I know the listItem text that  right mouse button clicked on?
}

Answer 1

When you right click, you actually also select. So that means you can just do:

    private void MenuItem_Click(object sender, RoutedEventArgs e)
    {
        string selectedListBoxItemText = ((ListBoxItem)listBox1.SelectedItem).Content.ToString());

        // do your thing
    }
