列表框以及如何对所选项目执行操作

Question

Hi I have this program Im trying to make

but now Im trying to add an option to delete items ( only the selected ones ).

thanx in advance

Answer 1

To delete the selected items:

while (listBox1.SelectedIndices.Count > 0)
    listBox1.Items.RemoveAt(listBox1.SelectedIndices[0]);

Answer 2

protected void Button2_Click(object sender, EventArgs e)
{
    for(int i = ListBox1.Items.Count -1; i>=0; i--)
    {
        if (ListBox1.Items[i].Selected)
        {
            ListBox1.Items.Remove(ListBox1.Items[i]);
        }
    }
}

This should work for deleting also
