Hi,

accessing ListBox's SelectedItem will return the currently selected item. There's also SelectedIndex, which will return the list index of currently selected item. If it returns -1, no item is selected.

You can use the ListBox.SelectedItem property to retrieve the selected item. This is null when no item was selected. Here is a little example:

private void button1_Click(object sender, EventArgs e)
{
object selectedItem = listBox1.SelectedItem;
if (selectedItem != null)
{
MessageBox.Show(this, "The selected item was: " + selectedItem);
}
else
{
MessageBox.Show(this, "Please select an item.");
}
}

ListBox1.SelectedItem.ToString() this will return the selected item in the list box.
