If you have checkedListBox1as checkedListBoxand your listBoxcalled listBox1, you should add this ItemCheck Eventfor your checkedListBox
如果你有checkedListBox1ascheckedListBox和你的listBox电话listBox1，你应该ItemCheck Event为你的checkedListBox
private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
{
if (e.NewValue == CheckState.Checked)
listBox1.Items.Add(checkedListBox1.Items[checkedListBox1.SelectedIndex]);
if (e.NewValue == CheckState.Unchecked)
listBox1.Items.Remove(checkedListBox1.Items[checkedListBox1.SelectedIndex]);
}
